Description
The Series 63BDL Constant-Differential Relays are used in conjunction with an external needle valve to provide
constant volume flow rates of liquids or gases over a continuously adjustable range.
For gas flow applications, compressibility must be considered if a constant mass flow is desired. Therefore, models are available for constant upstream or downstream reference pressure.
For liquids, which are not compressible, the constant volume flow will also be a constant mass flow, regardless of
upstream or downstream pressures. As such, mass flow is independent of pressure changes.
The relay’s needle valve determines rangeability and capacity.
Four models are available.
