LSQB type ultrasonic open channel flowmeterDetailed product description：

The LSQB ultrasonic open channel flowmeter can be used to continuously monitor the flow rate of sewage in open channels and accumulate the flow rate. It can also be used as a non-contact level gauge and is suitable for flow measurement in water conservancy, hydropower, environmental protection, and other industrial and agricultural open channel conditions.

The LSQB type ultrasonic open channel flowmeter uses ultrasonic waves to measure the water level height in the open channel weir in a non-contact manner, and the corresponding flow value is automatically calculated by a microprocessor. When measuring flow rate, the LCD displays instantaneous flow rate and cumulative flow rate; When measuring the liquid level, it displays the liquid level and upper and lower line alarm indicators. The digital memory is EEPROM, and the data inside the instrument will not be lost during power outages. The instrument is also equipped with explosion-proof probes specially designed for the petroleum and chemical industries to meet the measurement requirements of sewage flow in explosion-proof areas (explosion-proof grade ia Ⅱ BT6), especially suitable for flow measurement of oily wastewater. For the convenience of users, we can provide customers with Bacher slots and display heads for open channel flow meters, or design triangular weirs and rectangular weirs for free.
