Photoelectric direct reading single flow meter

I. Use: It is used to measure the total amount of drinking water flowing through the tap water pipe and transmitted to the secondary instrument through the M-BUS or 485 bus.

2. Features: Built-in CPU, memory chip and communication module. Power is supplied only when water meter data is collected. The word wheel code of the water meter is read by the photocell, and the number is generated by the CPU and output by the M-BUS or 485 bus.

3. Conditions of use: cold water table water temperature ≤30℃ Hot water table water temperature ≤90℃ Water pressure ≤1Mpa Water meter can not be immersed in water

4. Signal type: LXSY-15 ~ 40E 4-bit photoelectric coding

Maximum allowable error: 1. The maximum allowable error in the low area from the minimum flow rate including (Q1) to the boundary flow rate excluding (Q2) is ±5%.2. The maximum allowable error in the high zone from including flow rate (Q2) to including overload flow rate (Q4) is ±2% for cold water meters and ±2.5% for hot water meters.

Installation requirements: the water meter must be installed horizontally, so that the reading of the water meter is in the direction of the upward arrow and the direction of the water flow; Flush the pipe before installing the water meter; The water meter must be installed in a dry environment that is convenient for disassembly and maintenance. It is recommended to install it in a dedicated water meter box. Valves must be installed before and after water meters.

7. Main technical parameters: pressure level: MAP10; Pressure loss rating: △p63; Upstream flow field sensitivity level: U10; Downstream flow field sensitivity level: D5; Climatic and mechanical environment grade: B; Electromagnetic environment level: E1 level; Unmeasurable reverse flow.
