Inline Mass Flow Meters

Irrespective of pressure and temperature, the EE771 flow meter registers mass flow, volumetric flow or standard flow.

The flow meter can be used effectively to measure the consumption of compressed air, nitrogen, oxygen, CO2, helium or other non-corrosive gases.

The assembly concept with the ball valve permits rapid installation and removal with only a short interruption of the flow.

The heart of the flow meter is an E+E hot-film sensor element that, thanks to its high immunity to contamination, guarantees exceptional long-term stability and outstanding accuracy even under the harshest operating conditions.

The flow meter’s extensive measuring range from 0.5 to 200 Nm/s (1: 400) and fast response characteristics make it possible to carry out measurements throughout the entire supply system with one and the same device.

Even the smallest flow rates are accurately recorded – an essential prerequisite for calculating consumption costs or for finding leaks.

At the factory, every flow meter undergoes a strict calibration procedure on a flow calibration installation at a pressure of 7 bar.

The outstanding measuring accuracy is confirmed by the calibration certificate that comes with the device.

Bus interface for Modbus RTU or M-Bus: Optionally, the flow meter is available with an additional bus interface for MODBUS RTU or M-BUS (Meter-Bus).
