Storage building radio metering devices
Moisture refers to the presence of a liquid, generally water, in minute amounts. Moisture meters are the class of instruments that are able to measure the trace amounts of moisture in solids, gases and hydrocarbon liquids. Controlling moisture is vital as water vapor above certain levels can lead to condensation, corrosion, mold or other issues. Each material and application is affected differently by moisture and each has a range of moisture most suitable for it. Depending upon the application or material, too little moisture can be as bad as too much moisture.VIDEO ON THE TOPIC: 6 Meter Squalo Antenna Build

Automatic meter reading AMR is the technology of automatically collecting consumption, diagnostic, and status data from water meter or energy metering devices gas, electric and transferring that data to a central database for billing, troubleshooting, and analyzing.
This technology mainly saves utility providers the expense of periodic trips to each physical location to read a meter. Another advantage is that billing can be based on near real-time consumption rather than on estimates based on past or predicted consumption. This timely information coupled with analysis can help both utility providers and customers better control the use and production of electric energy, gas usage, or water consumption.
AMR technologies include handheld, mobile and network technologies based on telephony platforms wired and wireless , radio frequency RF , or powerline transmission. With touch-based AMR, a meter reader carries a handheld computer or data collection device with a wand or probe.
The device automatically collects the readings from a meter by touching or placing the read probe in close proximity to a reading coil enclosed in the touchpad. When a button is pressed, the probe sends an interrogate signal to the touch module to collect the meter reading.
The software in the device matches the serial number to one in the route database, and saves the meter reading for later download to a billing or data collection computer. Since the meter reader still has to go to the site of the meter, this is sometimes referred to as "on-site" AMR. Another form of contact reader uses a standardized infrared port to transmit data. AMR Hosting is a back-office solution which allows a user to track their electricity , water , or gas consumption over the Internet.
All data is collected in near real-time, and is stored in a database by data acquisition software. The user can view the data via a web application, and can analyze the data using various online analysis tools such as charting load profiles, analyzing tariff components, and verify their utility bill. Radio frequency based AMR can take many forms. The more common ones are handheld, mobile, satellite and fixed network solutions.
In a two-way or "wake up" system, a radio signal is normally sent to an AMR meter's unique serial number, instructing its transceiver to power-up and transmit its data. The meter transceiver and the reading transceiver both send and receive radio signals. This means the reading device can be a receiver only, and the meter a transmitter only.
Data travels only from the meter transmitter to the reading receiver. There are also hybrid systems that combine one-way and two-way techniques, using one-way communication for reading and two-way communication for programming functions. RF -based meter reading usually eliminates the need for the meter reader to enter the property or home, or to locate and open an underground meter pit.
The utility saves money by increased speed of reading, has less liability from entering private property, and has fewer missed readings from being unable to access the meter. The technology based on RF is not readily accepted everywhere. In several Asian countries, the technology faces a barrier of regulations in place pertaining to use of the radio frequency of any radiated power.
For example, in India the radio frequency which is generally in ISM band is not free to use even for low power radio of 10 mW. The frequency band of 2. Initiatives in radio frequency AMR in such countries are being taken up with regulators wherever the cost of licensing outweighs the benefits of AMR.
This is sometimes referred to as "walk-by" meter reading since the meter reader walks by the locations where meters are installed as they go through their meter reading route. Handheld computers may also be used to manually enter readings without the use of AMR technology as an alternate but this will not support exhaustive data which can be accurately read using the meter reading electronically.
Mobile or "drive-by" meter reading is where a reading device is installed in a vehicle. The meter reader drives the vehicle while the reading device automatically collects the meter readings. Often, for mobile meter reading, the reading equipment includes navigational and mapping features provided by GPS and mapping software. With mobile meter reading, the reader does not normally have to read the meters in any particular route order, but just drives the service area until all meters are read.
Satellite transmitters can be installed in the field next to existing meters. The satellite AMR devices communicates with the meter for readings, and then sends those readings over a fixed or mobile satellite network. Some systems operate with U. Devices such as the Smart Thermostat permit a utility to lower a home's power consumption to help manage power demand.
The city of Corpus Christi became one of the first cities in the United States to implement citywide Wi-Fi , which had been free until May 31, , mainly to facilitate AMR after a meter reader was attacked by a dog. This narrow-band signal has much greater range than Wi-Fi, so the number of receivers required for the project are far fewer. Special receiver stations then decode the narrow-band signals and resend the data via Wi-Fi. Most of the automated utility meters installed in the Corpus Christi area are battery powered.
Wi-Fi technology is unsuitable for long-term battery-powered operation. PLC is a method where electronic data is transmitted over power lines back to the substation, then relayed to a central computer in the utility's main office.
This would be considered a type of fixed network system—the network being the distribution network which the utility has built and maintains to deliver electric power. Such systems are primarily used for electric meter reading.
Some providers have interfaced gas and water meters to feed into a PLC type system. This technology was a spin-off of the automatic telephone line identification system, now known as Caller ID. In , Mr. Paraskevakos was awarded a U.
For this approach, Mr. Paraskevakos and Metretek were awarded multiple patents. The primary driver for the automation of meter reading is not to reduce labor costs, but to obtain data that is difficult to obtain.
In many areas, consumers have demanded that their monthly water bill be based on an actual reading, instead of for example an estimated monthly usage based on just one actual meter reading made every 12 months. What was once a need for monthly data became a need for daily and even hourly readings of the meters. Consequently, the sales of drive-by and telephone AMR has declined in the US, while sales of fixed networks has increased. The trend now is to consider the use of advanced meters as part of an Advanced Metering Infrastructure.
Originally AMR devices just collected meter readings electronically and matched them with accounts. As technology has advanced, additional data could then be captured, stored, and transmitted to the main computer, and often the metering devices could be controlled remotely. This can include events alarms such as tamper, leak detection, low battery, or reverse flow.
Many AMR devices can also capture interval data, and log meter events. The logged data can be used to collect or control time of use or rate of use data that can be used for water or energy usage profiling, time of use billing, demand forecasting, demand response , rate of flow recording, leak detection , flow monitoring, water and energy conservation enforcement, remote shutoff, etc.
Advanced metering infrastructure , or AMI is the new term coined to represent the networking technology of fixed network meter systems that go beyond AMR into remote utility management. The meters in an AMI system are often referred to as smart meters , since they often can use collected data based on programmed logic. The resolution, passed in February ,  acknowledged the role of AMI in supporting the implementation of dynamic pricing and the resulting benefits to consumers.
The resolution further identified the value of AMI in achieving significant utility operational cost savings in the areas of outage management, revenue protection and asset management. The resolution also called for AMI business case analysis to identify cost-effective deployment strategies, endorsed timely cost recovery for prudently incurred AMI expenditures and made additional recommendations on rate making and tax treatment of such investments. Advanced metering systems can provide benefits for utilities, retail providers and customers.
Benefits will be recognized by the utilities with increased efficiencies, outage detection, tamper notification and reduced labor cost as a result of automating reads, connections and disconnects.
Retail providers will be able to offer new innovative products in addition to customizing packages for their customers. In addition, with the meter data being readily available, more flexible billing cycles would be available to their customers instead of following the standard utility read cycles. With timely usage information available to the customer, benefits will be seen through opportunities to manage their energy consumption and change from one REP to another with actual meter data.
Because of these benefits, many utilities are moving towards implementing some types of AMR solutions. The benefits of smart metering for the utility.
Construction practices, weather, and the need for information drive utilities in different parts of the world towards AMR at different rates. AMI in Australia has grown from both government policy which sought to rectify observed market inefficiencies, and distribution businesses who looked to gain operational efficiencies.
In July , there was a mandated program being planned in Victoria for the deployment of 2. The anticipated peak installation rate of AMI meters was 5, per day across Victoria. The program governance was provided by an industry steering committee. In the Victorian Auditor General undertook a review of the program and found that there were "significant inadequacies" in advice to Government and that project governance "has not been appropriate".

AMR uses wireless radio frequency technology to collect meter reading data remotely using low frequency radio waves and these radio waves are generated by a battery powered device called an Encoder-Receiver-Transmitter ERT. For most customers, ERTs will be installed by replacing the touchpad they currently have using the same wires. Some customers will have older meters that will also need to be replaced as they cannot be converted for use with AMR technology.
In most cases the consumption is measured in order to allocate energy costs among the residents or users in a fair way. This means the energy consumption registered by every meter will periodically also need to be read out. Traditionally a person would come by and required access to every meter to list the consumption since the previous read out. Nowadays more efficient methods to register the consumption are available.
