vortex flow meter / for liquids / precision

Flow measurement device using the vortex measurement principle
●High precision
●High overload protection
●No moving parts
●Rapid installation and removal thanks to clamp fastening
●Various connections using building block system
Characteristics
A narrow triangular body (1), which goes through the complete
cross-section of the measurement pipe, creates vortices in the
medium when there is a flow (Kármán vortex street, vortex effect).
The frequency of the vortex is proportional to the flow, and is
detected using a piezo-sensor (2), which lies behind the triangular
body. The complete unit, vortex body, and detector are designed as
a plug-in unit (3), and are inserted into the pipe. Here, a lightning
fast separation between measurement pipe and the complete
measurement unit is possible.
The vortex flow meter requires a run-in length of 5..10 x D in order
to achieve its specified accuracy. If deposits are to be expected,
sensor and electronics should not be installed underneath. It should
be ensured that the sensor is installed in the direction of the flow
arrow. If the sensor is to be cleaned, the clamps should be
released, and the device removed (the pipe should be
pressure-free for this). It should be ensured during cleaning that the
oscillating vortex body is not exposed to impact (in the moulded
part there is a sensitive piezo-ceramic sensor, which can break).
