Battery Powered Clamp On Water Flow Meter

Battery powered clamp on water flow meter is developed from our latest low power platform. It is designed on the technology of transit-time principle. The water flow meter can be used for the application where no external power is available. In some places, solar-power module may have risk of being damaged and stolen. Meanwhile, clamp on flow transducers doesn’t require to cut pipe and welding work. A common people can install the flow meter without any skill.

The water flow meter has a built-in battery pack with 4-10 years working life. The battery pack is 3.6Vdc and easy to replace. Different battery pack may have different working life.  There are 2 kinds of electronic converters, one is IP65 class and the other is IP68 class. Usually, IP65 is as default.

The clamp on water flow meter can be used to measure clean water,tap water, irrigation water, alcohol,potable water, pure water, sea water, and other lightly-polluted water,etc.If require for other liquid flow measurement, please contact us for customization.

Our battery powered clamp on  water flow meter should be the first releasing item in the market.It has been a chanllenging job to develop clamp on ultrasonic water meter on battery power.  Clamp on flow technology usually requires high sample period and sampling group datas, and this requirement alwyas costs bigger power consumption. Thus the power capacity of built-in Li battery can’t bear big power consumption. That’s why there is no such product released before us. In order to solve the problem, our engineers have been working hard for tens of years. The product have been developed for several generations.

Why the Battery Powered Water Flow Meter ?

Firstly, water meters have mechanical type and electronic type. Mechanical type belongs to outdated technology,thus no discuss it.

For battery powered electronic water meters,e.g.ultrasonic water meters, they usually use common technology. So in order to ensure the performance, they don’t allow users to change parameters,e.g. date/time, flow measurement unit, even re-calibrate function. An electronic water meters will be used for several years. If the functions above are not open, users can’t re-calibrate it. If want to change several function, must get permission and authorization of software. The worst thing is that can’t be changed, and have to return the water meter to manufacturer.  This will be very trouoble and increase much cost for after-sale service. Why those manufacturer  can’t allow to modify?  The reason is their used common technology and can’t ensure their performance.  Once function is changed, the whole system can’t ensure its qualified performance.

But our battery powered water flow meter is different. Ours allow  allow users to re-calibrate, to set time/date, to set flow unit,etc. Our water flow meters have been developed on  industrial class standard and don’t need to worry it. Thus, our battery powered ultrasonic water meters will be your reliable and ideal choice,especially for international customers.
