Bell Proover Type- Accuracy and Pressure


Bell Proover Type- Accuracy and Pressure

GBP-4/GBP-6 bell proover test facility for gas meter is a new generation automatic test facility with high accuracy, high efficiency and good stability. Bell proover is a main standard. It adopts optical-electricity encoder to convert pulse signal.

The test facility can carry out automatic test towards G1.6, G2.5, G4.0 diaphragm gas meter according to JJG577-2012. The system is with dynamic image sampling, bar code scanning input, auto receive reed switch and pulse signal of gas meter, auto compensation for temperature and pressure, error judgement, data query, storage and printing function.
