The E+H Proline Promass A 300 is a Coriolis flow meter designed for continuous process control in very demanding applications requiring measurement of lowest flow rates and high pressure. Its unique self-drainable single-tube system enables accurate measurement of liquids and gases at flow rates from 0 to 450 kg/h. Nominal diameters DN 1 to 4 (1/24 to 1/8in).

Liquid mass flow error is ±0.1%; gas mass flow error ±0.35%; density error ±0.0005 g/cm³. Maximum process pressure 430.9 bar (6250 psi). Medium temperature range -50 to 205°C. Wetted materials: stainless steel 1.4435 (316/316L) or Alloy C22.

Compact dual-compartment housing accommodates up to 3 I/Os. Backlit display with touch control and WLAN access enables easy operation. Remote display available. Heartbeat Technology ensures measurement reliability and compliant verification. IP66/67, type 4X enclosure. Suitable for all industries requiring precise low-flow measurement.
