3″ water meter with pulse output
The pulse output water meter is a water meter with a very unique design.
It has the characteristics of passive signaling. A square wave signal can be output without a power supply. The distance reached one kilometer. And the transmitted signal is very accurate.
The water meter has a self-retaining function. Avoid more possibility of false signal. It can ensure that the signal has no errors.
Prevent all kinds of water theft from happening.
The service life is also very long, and the service life of the remote transmission part can be as long as ten years.
The water meter supplied by Sino-Inst can be configured with pulse output. When you place an order, please confirm with our sales engineer.

The types of water meters can be divided by the principle of measurement, the common types are:
a) Mechanical water meter:
Measuring sensors, calculators and indicating devices are all water meters with mechanical principles and structures. There are mainly speed water meters and volumetric water meters.
b) Mechanical water meter with electronic device:
The mechanical water meter with complete structure is retained, and the water meter with an electronic device is installed on this basis, mainly including IC card water meter and remote water meter.
The measuring sensor of the mechanical sensor electronic water meter is composed of a sensor based on the principle of mechanical motion and a sensor element that can convert the mechanical motion into an electrical signal and input into the calculator. Both the calculator and the indicating device are electronic components, such as a vortex (impeller) wheel electronic water meter.
