Ultrasonic Open Channel Flow Meter
INTRODUCTION
The physical quantity directly measured by the open channel flow meter is the liquid level. Water measuring weir will be installed at open channel and it’s for measure water flow.The measuring water weir converts the flow rate in the open channel into the level of the liquid level.The meter measures the water level in the water tank, and then calculates the instantaneous flow rate according to the relationship between the water level and the flow rate of the corresponding water tank.

| Cumulative flow can be queried according to the year, month, day, hour | |
| Output signal: | (4-20) mA (transmission instantaneous flow) and Rs485 (transmission instantaneous and cumulative flow) |
| Working temperature: | -20 ° C ~ 55 ° C |
| AC or DC power supply: | AC: 220V 50HZ, DC power supply DC (12-36) V 3W |
FEATURE
1. Sewage foam has no influence on its measurement, and certain impurities are allowed.
2. Non-contact measurement, corrosion resistance and long service life.
3. PVC or stainless steel can be selected for the material of Bap measurement trough/metering weir plate.
4. Open self-flowing type flowmeter, which can measure the flow of partial pipes.
5. The sensor is assembled with imported components.
6. Memory function after power failure, data retention for ten years.
Application
Used in conjunction with a water gutter to measure the flow of water in an open channel. It is mainly used to measure the flow rate of sewage discharge ports and urban sewers in sewage plants and enterprise liquid units.
