A method of making a pipe section structure for ultrasonic water meters

The ultrasonic water meter is a new type of water meter that detects the time difference caused by the change in speed of the ultrasonic beam as it propagates downstream and upstream in the water, and analyses and processes the flow rate of the water to further calculate the flow rate of the water. What is the working principle of ultrasonic water meter? What are the advantages and disadvantages of ultrasonic water meters?

Advantages and disadvantages of ultrasonic water meters

As water resources are becoming scarce,the demand for water measurement is increasing. The ultrasonic water meters are newly developed according to the national water meter standard GBT 778-2007 and the intemational water meter standard ISO-4064-1:2005,CJ-T188-2018 and EN1434.At the same time, it has a battery-powered super-long service life of large and small caliber ultrasonic water meter series.

Ultrasonic heat meter

Ultrasonic heat meter is a meter that measures the flow rate by ultrasonic method and displays the heat energy released or absorbed by the water flowing through the heat exchange system; it uses the physical quantities measured by two sensors to obtain the calorific value.

Several ways of packaging PCB circuit boards

1. PCB boards need to be vacuum packed in colourless air bead plastic bags, the bags should be accompanied by the necessary desiccant to ensure that the bags are packed tightly. Can not be in contact with wet air, so as not to be affected by the PCB surface spray tin, accumulation of gold and pad oxidation, to the detriment of production.
