Product Description

Remote meter reading, stable performance, accurate meter reading, high measurement accuracy.
Applicable to: all kinds of buildings and residential water supply measurement.
It can be combined with remote control valve, data collector, concentrator and management software to build "water metering intelligent management system" to realize water metering intelligent management.

Description

LXSGY/R type direct-reading remote water meter is a kind of measuring instrument that adopts photoelectric technology to measure the total volume of water flowing through the tap water pipeline.That new water meter, with new technology, novel design, reasonable, excellent material selection, beautiful appearance, precision assembly, easy maintenance.

Features
 

1. The non-contact sensor does not affect the original performance of the mechanical water meter
2. The infrared countermeasure is adopted to enhance the ability of anti-jamming.Non-mechanical contact mode, will not cause the phenomenon of random code reading due to mechanical loosening.
3. Low power consumption design, only when reading power supply.
4. Special coding mode, no dead zone of reading, word wheel rotation to any position can keep the mechanical reading and electronic reading consistent.
5. Adopting advanced data coding and checking method, communication reliability is high
6. Can be combined with the meter reading system, the establishment of remote meter reading management system, truly achieve meter reading automation

Installation and maintenance
 

1. Choose the diameter of water meter, should be decided according to pipe and use flow rate, and unfavorable use hot water
2. The installation location should avoid exposure, freezing, pollution and water flooding for easy disassembly and meter reading
3. The meter must be installed horizontally so that it literally faces up and that the arrow on the case is in the same direction as the flow
4. Before the new installation of pipes, be sure to wash the stones, silt, hemp and other debris in the pipe clean before installing the water meter, so as not to cause water meter failure
5. To measure correctly, the tap should be higher than the meter
6. Maximum pressure loss: 0.063Mpa
