Rotor liquid seal remote transmission cold water meter
The LXSY-15F-32F rotor liquid seal remote transmission cold water meter is a water metering instrument that uses the rotor liquid seal water meter as the base meter, achieves electromechanical conversion through non-magnetic sensing technology, and uses wired communication technology for data remote transmission to centrally manage the water meter.
1. The messaging module and base table adopt a separate structure; The power supply battery is independently packaged for easy battery replacement;
2. Adopting the current mainstream M-Bus transmission technology, it has high anti-interference ability and stable and reliable signal;
3. The DN15 to DN20 signaling positions use 1L measurement, while the DN25 to DN32 signaling positions use 10L measurement, with high measurement accuracy;
4. The base table adopts an independent trust pointer, which does not affect any readings;
5. A new non-magnetic acquisition method and special precision algorithm are used to ensure the accuracy of demagnetization and counting for the counting problems often caused by water flow backflow, shaking, and magnetic interference during the use of the water meter.
