Product details
name:LXS-15E~50E rotary wet camera cold water meter
Purpose:This series of water meters is used to measure the amount of cold water flowing through the tap water pipeline for drinking in households or residential units.
Usage conditions:
Temperature level: T30
Water pressure level: MAP 10 / MAP 16
Pressure loss level: △ P 63
Indication error limit:
From the low zone including the minimum flow rate (Q1) to excluding the boundary flow rate (Q2) ± 5%
From high zone cold water including boundary flow (Q2) to high zone cold water including overload flow (Q4) ± 2%, hot water ± 3%
Characteristics and main technical parameters:
Multi flow rate, rotor type, high measurement accuracy, small starting flow rate, easy to read.
Stable and reliable performance, long service life, beautiful appearance, strong universality of water meters, easy replacement and maintenance.
This series of watch cases can be made of copper, iron, stainless steel, engineering plastics, and aluminum alloy composite materials.
The camera watch is composed of a camera sensor mounted on a base watch through structural components
The advantages of a fully split structure are:
The circuit module is not under pressure, preventing faults caused by water ingress into the sealed chamber.
During the six-year mandatory inspection of water meters, the camera sensor can be reused.
Base table applicable: 15 caliber, 20 caliber
Data error: No error (actual on-site photos)
Communication method: M-bus
Communication parameters: 9600bps 8 N、1
Communication distance: ≤ 1000 meters
Power supply mode: instantaneous bus power supply for meter reading
Working voltage: DC24~36V
Static current: 1.2mA
Working current: 100mA
Automatic white balance, automatic exposure, and automatic gain ensure high-quality images
A single unit collection box can accommodate up to 100 P-type cameras
A single camera can connect to 6 buses, with a total of 600 P-type cameras
The series has strong universality and is easy to replace and repair; Accurate measurement and durability.
