WORKS WITH ANY FLOW METER
Pressure differential devices, ultrasonic meters, turbine and Vortex meters, mass flow meters, and many more…
UNIFLOW-200 can be configured to perform the flow calculation for a very wide range of flow meters. Besides the standard differential pressure devices (orifice plate, nozzle, Venturi tube according to ISO 5167) other devices such as Annubar, V-Cone, segmental orifice plate, or a flow meter with power characteristics (e.g. Parshall flumes) can also be configured.
Flow calibration data (flow coefficient vs. flow rate) can be entered for non-standard devices.
For gas flow metering devices with pulse output (turbine meter, Vortex meter) dual pulse input is provided. The continuous comparison of the main and check pulse trains allows instant detection of turbine meter blade damage. Pulse integrity check according to ISO 6551 level B is provided for liquid turbine meters.
Ultrasonic meters can be connected to the flow computer via pulse input like a turbine meter. It is also possible to use the serial link to acquire the flow information from ultrasonic meters. The ultrasonic meter is inherently bidirectional and therefore the UNIFLOW-200 distinguishes the forward and reverse flows and displays and totalizes them in separate streams.
Error curve correction
Error curve correction is available for the flow calibrated flow meters. The error correction method can be – linear interpolation with up to 16 error curve points, or – polynomial interpolation with up to 6th power. The log(flow rate/viscosity) vs. K-factor error curve correction is also available for liquid turbine meters.
