Calibration
FLUXUS is a very reliable instrument. It is manufactured under strict quality control, us-
ing modern production techniques. If installed as recommended in an appropriate loca-
tion, used cautiously and taken care of conscientiously, no troubles should appear. The
flowmeter has been calibrated at the factory and usually, a re-calibration of the flowmeter
will not be necessary. A re-calibration is recommended if
• the contact surface of the transducers show visible wear or
• the transducers were used for a prolonged period at a high temperature (several
months >130 °C for normal transducers or > 200 °C for high temperature transducers).
The flowmeter has to be sent to FLEXIM for recalibration under reference conditions.
The display does not work at all or always fails
Make sure that the correct voltage is available at the terminals. The voltage is indicated
on the metal plate below the outer right terminal. If the power supply is ok, the transduc-
ers or an internal component of the flowmeter are defective. Transducers and flowmeter
have to be sent for repair to FLEXIM.
