Product Description
Partial filled flow meter is an automatic flow measuring instrument that continuously measures the fluid flow in open pipelines (such as half-pipe flow sewage pipelines and large-flow pipelines without overflow weirs) using the velocity-area method. It can measure and display instantaneous flow, flow velocity, cumulative flow and other data. It is especially suitable for the needs of metering places such as municipal rainwater, waste water, sewage discharge and irrigation water pipelines.
Features
- Measurement of open non-full pipe flow, and can realize forward and reverse bidirectional flow measurement.
- Continuous measurement of municipal rainwater, waste water, sewage discharge and irrigation water pipelines and other places.
- Flow velocity measurement range is 0.05-10m/s, the accuracy is high, not affected by downstream, direct flow, and blockage.
- Large screen and backlight LCD display can clearly read the measurement data even under strong light or at night.
- Display instantaneous flow, flow rate, cumulative flow, etc.
- With power outage timing, counting and clock functions.
