The Diaphragm meter is a true positive displacement meter, which measures the consumption of natural gas while ensuring that there is no loss of gas during measurement. A diaphragm meter is used at lower varying flow rates especially when accuracy needs to be guaranteed. Barchard Engineering Ltd. sells a variety of diaphragm meters, which are used in different applications and at different flow rates.
The Rotary meter is used in industrial applications (i.e. higher loads of gas) when the flow rate is constant. Barchard Engineering Ltd. sells a variety of styles of rotary meters which operates at various maximum allowable pressures.
The Turbine meter operates under the same principle as a Rotary meter, however, it is utilized when flow rates are very high. Barchard Engineering Ltd. sells numerous different turbine meters, to meet a variety of needs.
