The EE776 is a thermal mass flow meter dedicated for monitoring compressed air, nitrogen, CO2 or other non-corrosive and non-flammable gases. It can be employed in pipes from DN50 to DN700 (2" to 28") and at up to 16 bar (232 psi).
The EE776 flow meter set new standards in terms of safety and easy assembly. The patented non-return protection combines three functions in one device:
The probe can only be moved in one direction during installation, and it cannot return at all, even if it is released.
By means of an encapsulated O-ring, the pressurized gaz cannot leak during probe mounting.
The precise positioning with respect to immersion depth and orientation is easy to perform, guaranteeing accurate measurement results.
An optional ½" ball valve enables the installation and removal of the probe without interruption of the gas flow. Every EE776 flow meter undergoes a precise factory calibration procedure at a pressure of 9 bar (130 psi), the corresponding calibration certificate is included in the standard scope of supply.
EE776 features two outputs which can be configured as analogue (current or voltage), alarm or pulse output for consumption metering. The EE776 flow meter is available with an additional MODBUS RTU or M-BUS (Meter-Bus) interface.

Modular, compact in-line flow meter for DN15, DN20 and DN25
With three different gauge mounting blocks, one and the same transmitter unit can be employed in pipes with diameter DN15, DN20 and DN25. Outstanding measuring accuracy due to multi-point factory adjustment at the common compressed air pressure 7 bar (102 psi).
Inline mass flow meter DN15 - DN50
The inline mass flow meter for DN15 - DN50 (1/2" - 2") and up to 16 bar (232 psi). The measurement ball valve permits rapid installation and removal with only a short interruption of the flow.
Inline Mass flow meter DN40 – DN80
Multifunctional inline mass flow meter for DN40 - DN80 (1 1/2" - 3") up to 40 bar (580 psi). Gauge mounting block with hot tap valve for installation and removal without interruption of the flow. Mounting possibility for pressure and dew point sensors.
