Water Meters & Remote Meter Reading Systems
The company’s product offering includes a very wide range of high-precision meters, from ½” to 8” diameter, which comply with the international MID, ISO2005 and EN14154 standards. Most meters are approved by the Standards Institution of Israel.
These products include multi-flow, Woltmann, combined, ultrasonic, and electromagnetic meters. All meters are prepared to include a transmission and remote reading unit.
The terminal unit enables data to be very reliably recorded from the mechanical reader, including cumulative counting, positive and negative alike. This data allows maximum matching to the mechanical meter’s reading, while also providing data on reverse flow, meter reversing and information allowing for calculation of true consumption if it is suspected that the water meter has been reversed.
The terminal unit has a wide range of indicators and alerts for particular statuses such as hidden leaks, burst pipes, water meter tampering, tilting, magnets, a weak battery in the terminal unit, and more.
Usually, the terminal units (transmission units) are installed inside the integrated meters supplied by Afcon. However, these transmission units also allow for external (non-integrated) connection to all types of water meters with output units. The external terminal unit may be connected to the meter in various ways, such as via pulses, the absolute encoder method, Modbus, or any other communication type. The wireless transmission protocol creates data redundancy as well as the ability to analyze errors and transmitted signal strength. The communication units are able to transmit in all types of populated areas, including high and low-density construction, and under very harsh ambient conditions, while still maintaining a high level of reliability.
Although the network’s transmission power is very low (10mW), it has a long range that sometimes reaches several kilometers. This minimizes the number of communication amplifiers required by the network. Data transmission lasts less than a second and occurs 4-5 times a day (usually depending on consumption). The data is transferred to the data server and is saved there in order to generate reports. There is also the option to receive consumption data online (upon request).
Even though the consumption transmissions are only sent a few times a day, system alerts reach the control center immediately.
