Dry Gas Meter Characteristics
This meter is of the volumetric positive displacement type. As such, almost all types of gas can be measured without influence from relative density, viscosity, etc. It does not moisten gas, so the measurement has no influence from vapor-pressure.
DC type for experimentation/environmental measurement
Adoption of synthetic materials has led to a compact and easily portable meter. LCD digital thermometer is built-in as standard.Type A has been discontinued for DC-1 and DC-2

DS type for large flow rate and fixed installation by gas pipe
Although the standard connection is for for gas pipe, connector for rubber tube is available as an option. Da pulse detector is built-in as standard.
