HLS45A flowmeter HLS452. Flow velocity and flow rate measuring instrument

Specification

1Speed measurement range:0.015～3.5m/s.

2Working water depth:0.05～3Rice. Due to the length limitation of the signal line, if the depth of water ingress exceeds6Rice needs to purchase additional long lines, sealed joints, and extended measuring rods from the factory. ）

3Working temperature:-10℃～+45℃.

4Flow rate,Flow calculation: Direct reading is completed by a flow meter measuring instrument.

5The relative mean square error of the entire instrument line is ≤2%.

6Number of signals per revolution of the instrument: four.

7Signal reception and processing: flow meter measuring instrument.

1、 The purpose and characteristics of the instrument

HRThe type measuring instrument is a secondary instrument that is matched with the flow meter produced by our factory, which uses Hall elements as rotor output signals. It can process, calculate, and display multiple flow rate signals output by this type of flow meter for one revolution. Suitable for irrigation areas, industrial wastewater discharge channels, hydrology, and field water resource measurement. This instrument is portable, with the characteristics of small size, light weight, easy operation, and economic practicality.
