Ultrasonic water meter working principle

The ultrasonic water meter adopts the time difference method to measure the flow. That is, an ultrasonic transducer is installed at the upstream and downstream of the measuring channel (pipe section) to transmit and receive ultrasonic signals.

Because the ultrasonic signal and the water flow signal are superimposed, the propagation speed of the sound wave is different in the forward and reverse flow. Therefore, the running time of the ultrasonic signal emitted by different transducers in the water is different. The fluid can be calculated by measuring the difference of the time The flow rate. Then it is converted into a flow rate, so as to realize the measurement of the flow rate.

There are two transducers on the top of the flow tube. Transducer A transmits an ultrasonic signal to transducer B (downstream), while transducer B transmits an ultrasonic signal to transducer A (countercurrent). Downstream and The countercurrent ultrasonic signal forms a certain time difference in the transmission process. In the case of the calibrated cross-sectional area of ​​the pipe diameter and the length of the standard measuring pipe, the flow rate of the meter is calculated by the calculation chip on the integrator.

Advantages and disadvantages of ultrasonic water meters

Ultrasonic water meter is a fully electronic water meter manufactured with industrial-grade electronic components using the principle of ultrasonic time difference. Compared with mechanical water meters, it has the characteristics of high accuracy, good reliability, wide range ratio, long service life, no moving parts, no need to set parameters, and installation at any angle.

The ultrasonic water meter has no moving or blocking parts in the tested pipeline, no wear, and low pressure loss. High sensitivity, can detect small changes in flow rate. At the same time, it has almost no requirements for the measured medium, has an extremely wide range ratio, and the ultrasonic water meter has a simple structure and is easy to maintain, which is very suitable for civil and industrial measurement.

But the stability of ultrasonic water meters is low.

Strap on flow meter X3 almost meets the measurement of different clean fluids: various acids, alcohols, chemical solvents, alcohol, drinking water, Coca-Cola water… etc.

Portable ultrasonic flow meter

Handheld ultrasonic flow meter realizes the non-contact measurement of liquid flow. Also often referred to as Portable Clamp-On Ultrasonic Flow Meter for Liquids.

Handheld Ultrasonic Flow Meter ( Model:2000H) has been successfully applied to measurement work in various industries. The measuring range is 20-6000mm (0.5-20 inches). A non-contact measurement method is adopted. Flexible operation and easy to carry. Conductive or non-conductive, corrosive or non-corrosive liquids can be measured. Various fluids: water, pure water, sewage, sea water, chemical fluids, river water, fuel Oil etc. can be measured.
