Description
Overview
GAOTek Open channel water ultrasonic flow meter with weir and flume which used together for measured the flow in the open channels. Mainly application is the outfall of sewage plant and the sewage of enterprises, city sewer and irrigation channels. The instrument produced by GAOTek uses ultrasonic waves through the air, non-contact method to measure. Compared with contact instruments, it has higher reliability and durability in the condition of sticky dirt, corrosive liquid.
Features
