The Vaisala DSC74B limits the flow rate with a fixed leak screw. The flow is optimized for pressures 3 to 10 barg. The fixed leak screw eliminates the risk of opening the leak screw fully by accident and this way emptying a gas vessel. The maximum flow can be increased, if needed, by removing the leak screw and adjusting the flow manually with the valve.

In the basic operation of the DSC74B, the gas flows to the sensor from the front and the outlet is on the side. To have the measurement done at atmospheric pressure, the inlet and outlet are reversed. Then the reducing parts (G3/8" -G1/2" or G3/8" - G1/4") on the outlet side help to protect the sensor from ambient humidity coming in.

The Vaisala DSC74B is compatible with the DM70, DMT132, DMT142, DMT143, DMT152, DMT242, DPT146, and DMT347 transmitters.
