Photoelectric Remote Reading Water Meter

The meter is a direct reading type water meter for remote reading with

application of photoelectric direct reading technology. It can realize

remote reading of metering of water use through the master system,

which effectively helps the management department solve the problem

of visting customers for meter reading and dramatically improves the

efficiency.
The large calibre photoelectric remote reading water meter is specially designed for harsh working ambient,suitable for metering of residential water or industrial water. ?
Features & Benefits:

1. Mechanical readout and electronic readout are accordant due to direct

reading from the dial register

2. Power supply is not needed during ordinary operations,no power

consumption,instant power source required only while meter reading

3. Use of advanced data coding and verification technology that assures

high communication reliability

4. Large flow capacity, small pressure loss, detachable construction for

easy maintenance & repair

5. Compatible with multiple communication protocols like DL/T 645,

CJ/T 188, Modbus or customized.

6. Satisfy the design requirements for electromagnetic compatibilities

(like EMC, ESD, EMI.etc) of electronic products

7. Compliance with GB/T 778.1~3-2007 national standard and

CJ/T 224-2012 urban construction industrial standard

8. As an option,our GPRS monitoring device can be equipped to realize

long-distance transmission through GPRS network
9. Electronic units and dial register parts are hermetically sealed in the cavity that formed by copper shroud and glass,resistant to corrosion of water and moisture,making it perfectly water-tight (IP68 rating)
?

Application

Measuring the volume of cold or hot water passing through the pipeline

?

Quality:
Data refer to LXLC-50-600 water meter
Water meter equipped with a Reed Switch Pulser which can be connected to remote reading systems. The Reed Switch Pulser sends out electric signals per a preset water quantity.
Comes in several model variation, which indicate different pulse rates. To choose the variation best suited to your needs as per below diagram.
