1. Sewage Doppler flowmeter

2. Instantaneous sewage flowmeter

The instantaneous sewage flowmeter can display the instantaneous flow rate and cumulative flow rate, measure the flow rate of sewage, and the sewage flowmeter Shanghai Menghui. The measurement principle of the sewage flowmeter is based on Faradays law of electromagnetic induction, which measures the volume flow of the conductive medium inside the induction measurement tube to calculate the flow volume. It adopts embedded technology of single-chip microcomputer to achieve digital excitation, and the bucket cover on the sewage flowmeter adopts CAN fieldbus, which is the first of its kind in China and the technology has reached the leading level in China. Sewage flow meters can not only meet on-site display requirements, but also output 4-20mA current signals for recording, regulation, and control purposes. They have been widely used in industrial technology and management departments such as chemical, environmental protection, metallurgy, medicine, papermaking, and water supply and drainage. In addition to measuring the flow rate of general conductive liquids, sewage flow meters can also measure the volumetric flow rate of liquid-solid two-phase flow, high viscosity liquid flow, and salt, strong acid, and strong alkali liquids.
