Battery powered clamp on water flow meter is developed from our latest version clamp on ultrasonic flow meters and based on the technology of transit-time principle, but both of them have several difference. The main difference is clamp on water flow meter can be powered by battery,but clamp on flow meter will have to be powered external AC or DC.

The battery powered clamp on ultrasonic water meter is mainly used to measure water flow,the water can be clean water,potable water, pure water,sea water,alcohol,light-degree dirty water,etc. Built-in battery for the water meter can work for about 4 years life. Meanwhile, the clamp on water flow meter  is made with IP68 protection class.

Our clamp on ultrasonic water meter with battery powered should be the first product in our country,even in the world.It is difficult to develop clamp on ultrasonic water meter powered by battery because clamp on flow measuring technology always requires very high sample period and sampling group datas, but this requirement also costs bigger power consumption. But the power capacity of built-in Li battery is always limited because of current battery technology. That’s why there is no such product released before us, even though western companies who don’t release such one.

Comparing other type water meters,clamp on ultrasonic water meter has many good unique advantages: no pipe cutting, no moving parts,no pressure loss,no risk of leakage,low cost maintenance,etc. Of course, in order to make the product have a wide applicaiton, we also release a version with battery and external DC power together. When use exeternal DC power, it will be clamp on ultrasonic flow meters.
