Ultrasonic flowmeter, energy meter simple operation, convenient installation, wide range of application, high measurement accuracy, affordable. Ultrasonic flowmeter and energy meter have good effect in HVAC engineering test and air conditioning circulating water measurement, and have been widely praised, and have become a convenient tool for HVAC engineering test, debugging, inspection and maintenance.

The portable ultrasonic flowmeter solves the problem of flow measurement of corrosive media with its non-contact measurement method, and is widely used in the chemical industry.

It is necessary to measure the circulating water flow in hydropower station. Since the pipe diameters that need to be measured belong to large models, namely DN6000 models and DN3000 models, after comprehensive analysis and demonstration of the flow to be measured and various types of flowmeters, it is finally believed that the more economical, applicable and feasible ultrasonic flowmeter can be used to solve the problem. Therefore, the ultrasonic flowmeter was selected to measure the circulating water flow accurately, and the corresponding problem was solved.

ooling water is one of the main energy sources in the production process of pharmaceutical companies, and the accurate measurement of cooling water directly affects the power cost of products. There are various types of cooling water such as -5 ℃ and 7 ℃, and there are inlet and outlet pipes with generally larger diameters; In addition, pharmaceutical companies need to frequently adjust their cooling capacity due to process requirements, and the amount of cooling water used is always fluctuating. Historical data analysis of flow meters can provide data support for the reasonable matching of cooling water usage and supply. As an energy supply unit, the power workshop must be able to accurately measure the amount of various cooling water used to correctly allocate and settle with each energy consuming unit.

The composition and properties of the sewage connected to the sewage treatment plant are complex. If a direct contact flow meter is used, it is inevitable that scaling or corrosion will occur inside the flow meter for a long time, which will affect the measurement. This requires the sewage flowmeter to have the following characteristics: (1) the measuring instrument for sewage discharge is preferably a non-contact measuring instrument; (2) The instrument has the characteristics of strong resistance to steam drum, easy installation, and low power consumption; (3) The sensing device is installed outside the sewage pipeline and does not require cutting off the pipeline.

Semiconductor factories require a large amount of water, including cooling water, drinking water, neutral water, chilled water, and sewage. Some of this water is non-conductive pure water, and in some cases, instruments are required to not pollute the production pure water. In addition, pipelines are made of plastic or metal materials.

Due to changes in production capacity, the company's brine pump power increased. After the power was expanded, the flow rate of the pump became unstable and the displayed flow rate did not reach the expected value. After inspection, it was found that the brine pumping station experienced significant vibration and the replaced frequency converter caused interference. The electrode of the electromagnetic flowmeter is corroded by brine, resulting in a decrease in detection accuracy; After replacing the high-power frequency converter, electromagnetic interference caused significant fluctuations in the detection value of the electromagnetic flowmeter, and the brine flow rate could not be displayed correctly and stably.
