2019 new product Sandwich-typed Ultrasonic Water meter

The T3 series ultrasonic water meter is a new generation of smart water meter designed for agricultural irrigation and water resource monitoring. It is an all-plastic smart water meter with nylon as the main material. It is installed in the pipe by clamping the meter body which is only 50 mm in thickness between the two flanges of the pipe.

The new generation of T3 series ultrasonic water meter uses a technology similar to that of FLEXIM company’s ultrasonic flowmeter. The transit time difference is obtained through correlation calculation of captured signal waveform, thus featuring high precision, low drift, anti-interference, stability and reliability.

The smart water meter also uses a signal acquisition hardware with a dynamic range of 30dB, so it can resist medium scaling inside the pipe and is suitable for measurement of muddy water with sediments.

This smart water meter adopts waterproof sealant and can be immersed in water.

Compared with the traditional water meter, the new meter is smaller in size, lower in failure rate, more reliable in function and cheaper in price.
