EPSILON Flow meter for Insertion Between Flanges

Principle: EPSILON is used as primary elements in flow measurement of liquid and gas according to the differential pressure principle.

EPSILON flow meter with 5 holes combines a traditional single hole
orifice plate with a flow conditioner.

This means that straight pipe run up stream the flow meter can be
reduced from 20 times inner pipe diameter to 5 times inner pipe
diameter, which is crucial with limited space available.

Construction & installation requirements

Model EP1
The EPSILON flow meter model EP1 consists of a primary element based on the differential pressure principle, a flange manifold for double flanged valve manifold

Model EP2
The EPSILON flow meter model EP2 consists of a primary element based
on the differential pressure principle with an integrated 3 valve manifold

Model EP5
The EPSILON flow meter model EP5 consists of a primary element based
on the differential pressure principle with an integrated 5 valve manifold

The EPSILON flow meter can be mounted in a horizontal or vertical pipe.
For liquid flow in a horizontal pipe the electronics shall be mounted
below the pipe.
For gas flow in a horizontal pipe the electronics shall be mounted
above the pipe.

High accuracy of measurement is achievable even with short straight pipe runs upstream from the flow meter. The required straight pipe run is only 5 x inner pipe diameter
and 2 x downstream to maintain an accuracy of 1%

Is mass flow required due to changing process conditions ask for the
EPSIMAS mass flow meter data sheet.
Saturated and superheated steam is covered by EPSISTEEM flow meters
