Place of Origin: Liaoning China (Mainland) Brand Name: Danre brand Model Number: JW series

Specifications and Product Details:

APPLICATION

JW series mechanical type temperature compensation gas meter is suitable for measuring the flow-rates of town gas, natural gas, marsh gas, liquefied petroleum gas and air etc.

FEATURES

1. Accurate measurement and high sensitivity.

2. Adopting rubber diaphragm with performance of low temperature-resistance. The lowest working temperature can reach -30°C.

3. With internal mechanical type temperature compensation mechanism and this can compensate the measurement error of the gas meter results from temperature changes.

4. Adopting a series of new manufacturing technology such as automatic glue-applying technology, ultrasonic welding technology and resistance welding technology etc.

5. Adopting special surface treatment technology, it has strong corrosion resistance and long service life.
