What is the prospect of ultrasonic water meter function?
In recent years, the production and sales of most water meter companies have increased year by year, especially the smart water meter products and application systems have doubled. The proportion of smart water meters and mechanical water meters in the industry has doubled, and the total sales have also increased significantly.
The stepped water price policy has detonated the demand for water meters, and the ultrasonic smart water meter market has also risen. Ultrasonic water meters are new products and technologies that are prioritized in smart water meters. The ultrasonic water meter is a new type of water meter that detects the time difference caused by the speed change when the ultrasonic sound beam propagates upstream and downstream in the water, analyzes and processes the water flow rate, and further accumulates the water flow rate. Compared with mechanical water meters, ultrasonic smart water meters have the advantages of high precision, good reliability, wide range ratio, long service life, no moving parts, no need to set parameters, and installation at any angle.
