Battery Powered Insertion Water Flow Meter

Insertion ultrasonic water flow meter is developed from transit-time ultrasonic flow meter with insertion type transducers. Comparing with standard insertion water flow meter, its main advantage is battery powered (3.6VDC) with ultra low power consumption. The battery operated insertion ultrasonic water meter can be used for pipe size DN50mm and bigger. It has been cost-effective solution for accurate water flow measurement.

The insertion ultrasonic water meter is powered by built-in battery and the battery life may last for 6-8 years. As it is battery powered, it is mainly used to measure water and other clean stable liquid where external power is not available. Unlike mechanical flow meters, the insertion ultrasonic water meter has no moving parts and can have a longer working life.

Comparing with inline ultrasonic water meter, insertion ultrasonic water meter is lighter and easy to ship.

Comparing with clamp-on ultrasonic water meter, insertion ultrasonic water meter has a better accuracy.

In order to make insertion transducer installed easily, we have developed patented hot-tap installing tool. With this hot-tap installing tool, insertion ultrasonic water meter can be installed without flow stop.

Note:
(1).For carbon steel pipe or stainless steel pipe, the insertion transducers can be welded. Please kindly inform us while  order so that we can supply proper welding base.
(2).For pipe material that can’t be welded, e.g. PVC, copper, etc, it will require fixing strap.
