VENTURI-flowmeter EVR2000 for flow measurement in pipelines
VENTURI-flowmeter EVR2000 for flow measurement in pipelines
Designed according to DIN EN ISO 5167-4
Undisturbed straight pipeline
Designed for liquids, gases or light fibres
Very low deposition danger – suitable for transporting light fibres
2 X 8 pressure taps guarantee highest accuracy
Very low pressure drop
Can be combined with various measuring / control devices
Nominal widths, lengths and measuring ranges according to customer requirements
Optional: Pneumatic feed for cyclically blow the measuring points
Combined with transmitters of DA2000er series:
Large analog display (270 °) – Scale length 250 mm
Indicator in IP66 protective housing
Scale in m³ / h
Different limit indicator
Analog outputs 0 … 10 V or 4 … 20 mA possible (linear or square root)
Combination with a pressure switch (1.5 A / 250 Vac)
Our latest development is the EVR2000 an adaptation of the venturi principle.
In the latest development, we combine a specially designed steel tube, in the form of a classical venturi tube, with our DA2000 pressure indicator. We thereby enable a trouble-free flow measurement and increase the application possibilities of the venturi principle.
Besides the measurement of liquids and gases, we let you monitor, supported by air pressure „objects / particles“ such as fibers, polymers, cellulose and similar. In this way a production chain at various points is continuously monitored and the power efficiency obtained constant. The special design of EVR2000 ensures optimum flow and a free stay of the measuring point. Convinced we promise a very high disturbance life.

To increase the long-term stability of EVR2000 can optionally be equipped with a compressed air supply. This supplement prevents that the measuring points enforce through the smallest particles to 100%. The measuring points are blown out at regular intervals.
Of course, the device is manufactured as required by the customer, which nominal diameters and lengths are determined individually.
