Mass Flow Meters for Pipe Diameter DN15 to DN700

The various E+E flow meter models are suitable for pipe diameters from DN15 to DN700. The core of each device is the well proven E+E hot-film sensing element. Its high resistance to contamination leads to an excellent long-term stability. The factory adjustment at 7 bar (102 psi) or 9 bar (130 psi) working pressure ensures highest accuracy for every single E+E flow meter.

EE741 – Modular, Compact Flow Meter

For pipe diameters DN15 to DN50 and up to 16 bar (232 psi) working pressure

Thanks to its modular design, the EE741 flow meter can be used for various different pipe diameters. To do so, the transmitter is combined with the appropriate gauge mounting block:

 EE741: DN15, DN20, DN25
 EE741-N50: DN32, DN40, DN50

The transmitter can be mounted and removed at any time, without work on the pipeline. A longer operation interruption can be avoided. This construction facilitates periodical calibration of the measuring unit and its temporary use at several measuring points.

EE771 – Flow Meter with Measurement Ball Valve

For pipe diameters DN15 to DN50 and up to 16 bar (232 psi) working pressure

The EE771 flow meter impresses with a wide measuring range from 0.5 to 200 Nm/s (1:400).

The measurement ball valve permits easy installation and removal of the measuring unit with only a short interruption of the flow. It also facilitates the precise and reproducible positioning of the stainless steel probe in the pipeline.

For the version with remote probe, the electronics can be placed up to 10m away from the probe.

  • EE772 - Flow Meter with Gauge Mounting Block
    The EE772 flow meter with gauge mounting block allows for installation and removal of the probe without flow interruption.
  • EE772 Gauge mounting block with flow sensor
    The gauge mounting block enables precise positioning of the flow sensor in the pipeline.
  • EE772 Gauge mounting block with dew point sensor
    The gauge mounting block can also accommodate a dew point or pressure sensor.

EE772 – Multi-functional Mass Flow Meter with Gauge Mounting Block

For pipe diameters DN40 to DN80 and up to 40 bar (580 psi) working pressure

The EE772 is dedicated for applications where the process may not be interrupted.

The gauge mounting block with hot tap valve allows for installation and removal of the probe without interrupting the air or gas flow. A calibration of the sensor is thus possible at any time and without system downtime.

The gauge mounting block can also accommodate an additional dew point or pressure sensor, which simplifies considerably the monitoring of the compressed air quality.

EE776 – Insertion Flow Meter with Non-Return Protection

For pipe diameters DN50 to DN700 and up to 16 bar (232 psi) working pressure

The EE776 is dedicated for mass flow measurement in large diameter pipes. The patented non-return protection ensures safe installation and precise positioning of the probe under pressure.

The tapping sleeve allows for drilling into the pipeline under pressure and for mounting the EE776 without disturbing the process and without welding work.

An optional ball valve enables the installation and removal of the probe without flow interruption.

The Hot-film Anemometer Principle

Long Service Life and High Accuracy

The E+E flow meters are based on the hot-film anemometer principle. The main benefit of this measuring principle is the absence of moving parts. This makes the sensor wear-free and highly insensitive to mechanical influences such as shocks and vibrations. This leads to low maintenance and long service life.

Another benefit: the mass flow or the volumetric flow measured with a hot-film anemometer is independent of pressure and temperature. The devices can therefore be used at various pressures and temperatures without compensation.
