Ultrasonic open channel flowmeter
Ultrasonic open channel flowmeter is a new type of flow meter used to measure the sewage discharge of enterprise flow pipe (channel), referred to as "sewage flowmeter". It is widely used in the sewage discharge measurement of petroleum, chemical, textile and pharmaceutical industries, is one of the necessary instruments for urban pollution control and environmental protection departments to monitor sewage discharge, and is also a standing instrument for agricultural irrigation water discharge measurement in water conservancy departments.
The flowmeter adopts hydraulic flow measurement, ultrasonic position measurement, microcomputer processing, digital display and other technologies, can be installed in harsh environment, automatic metering, with high reliability and strong dry resistance. Easy installation and maintenance, simple reading.
It is based on the specific shape of the Basher metering tank/weir plate metering tank, to ensure that its certain liquid level height, to know a certain flow, the selection of Basher tank/weir plate metering tank as a specific flow channel, high measurement accuracy, easy installation, sensor measurement of liquid level height, through the MCU processing to obtain instantaneous flow and cumulative flow value, flow can be expressed as follows:
Q=KHn
Q: instantaneous flow rate (t/h) K: constant flow rate
H: Liquid level height n: n power value
The cumulative flow rate is obtained by the cumulative calculation of the instantaneous flow rate.
