Coriolis mass flow meter for low flows up to 50 kg/h

Coriolis mass flow meter dedicated to small flow rates. It simultaneously measures mass flow, density and temperature, from which the volume flow can also be calculated. The sensor is only available with a remote transmitter, which provides analogue output with HART®, binary, pulse and status outputs.

Features

• Measuring ranges from 0…20 kg/h to 0…50 kg/h
• Connections ½" NPT female, G ½ male, Gyrolok®/Swagelok® 6/8/10/12 mm compression fittings
• Measuring tubes in stainless steel 1.4571, flow body in 1.4404, secondary containment in aluminium or stainless steel
• Pressure up to PN400, temperature -40…+180 °C
• Accuracy ±0.1 % of reading (liquids), ±0.5 % (gases), ±0.005 g/cm³ (density), plus zero-point stability
• Very robust, vibration-resistant flow body with flexible housing and mounting options

Operating principle

Very low flows are often measured with single-tube sensors, which are more sensitive to external interference and require costly decoupling. This instrument instead uses two bent measuring tubes, with the coils mounted between the tubes rather than on them: the dynamic behaviour is less noisy and more predictable, allows higher operating frequencies and further isolates the measurement from external vibration.

Applications

Batching and measuring small flows of almost all liquids and of gases, including in environments subject to vibration and in hazardous areas.
