Partially filled flow meter is an automatic flow measurement instrument that continuously measures fluid flow in open pipes (such as half-pipe 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 particularly suitable for the needs of metering sites such as municipal rainwater, waste water, sewage discharge and irrigation water pipelines.
Features:
(1) Measurement of open non-full pipe flow, and can realize forward and reverse bidirectional flow measurement.
(2) Continuous measurement of municipal rainwater, waste water, sewage and irrigation water pipelines and other places.
(3) Flow velocity measurement range is 0.05-10m/s, accuracy is high, not affected by downstream, direct flow, and blockage.
(4) A large LCD screen and backlight can clearly read measurement data even in high light or at night.
(5) Display instantaneous flow, flow rate, cumulative flow, etc.
(6) With power outage timing, counting and clock functions.
