EL-FLOW® series Mass Flow Meters and Controllers for gas applications are truly unique in their capability to control flow ranges between 1 sccm and 1250 slpm full scale with pressure rating ranging between vacuum and 6,000 psi - all in one range of instruments. This versatility in flow ranges and in operating conditions has ensured that the EL-FLOW® series remains our most popular and field proven of instruments.

LIQUI-FLOW®  Mass Flow Meters and Controllers for liquids in ranges between 5 g/h and 20 kg/h (water equivalent) full scale. Flow meters only require a small differential pressure. Despite utilizing direct measurement (i.e. without a by-pass) the temperature rise of the fluid is minimal; approx. 1...5 °C. This greatly limits the danger of evaporation or degradation of the fluid.

The EL-PRESS series electronic pressure meters and controllers have a well-proven compact thru-flow design and are available in pressure ranges for 100 mbar up to 6,000 psi. A differential pressure transmitter can also be supplied in the range of 100 psi. The pressure controller performs with high accuracy and repeatability and can be specified for forward pressure control or backward pressure
control.

CORI-FLOW® utilizes a patented, advanced Coriolis type mass flow sensor to achieve unsurpassed performance, even with changing operation conditions in pressure, temperature, density, conductivity or viscosity. CORI-FLOW® is offered with or without an integral control valve but with both analog and digital communications.
