MV-RD906 Lens Antenna Radar Level Meter, 26 GHz

METRAVON MV-RD906 is a lens antenna radar level meter for liquid process vessels. This configuration uses a 76 mm PTFE lens, operates at 26 GHz and has a listed distance range of 0.2-30 m. It is a non-contact option for evaluating chemical tanks and agitated vessels where the antenna position, exposed materials and operating cycle need to be considered together.

Follow the liquid through the complete process cycle

Describe the liquid before and after mixing, heating or dilution. A quiet surface at commissioning may become turbulent or foamy when the agitator runs. Record agitator speeds, filling direction, vapour conditions and any deposits seen at the nozzle. A stable reading with the mixer stopped is not sufficient evidence for continuous control during production.

Decide how quickly the level signal must respond. Damping can reduce displayed fluctuations, but too much filtering can delay recognition of a real level change. Agree the required response with the control engineer and test it against the fastest expected filling condition; do not choose a setting only because it produces a smooth trend.

Check lens position, seals and cleaning exposure

Confirm the lens clearance through the actual nozzle bore and the position of its face relative to the nozzle outlet. Keep agitator blades, coils and the incoming liquid out of the intended beam path. If a stilling arrangement is proposed, have that assembly assessed for the selected radar rather than assuming any pipe improves the signal.

Review the PTFE, seal, flange and other exposed materials against the liquid concentration and cleaning procedure. The listed pressure and temperature limits must apply to the same ordered assembly. PTFE construction by itself does not establish hygienic certification, suitability for steam sterilisation or compatibility with every solvent.

Make the control-system test observable

For the 24 VDC two-wire 4-20 mA/HART version, record the local level, measured loop current and PLC value at the same test points. This separates a distance-measurement problem from an incorrect analogue conversion. With an RS485/Modbus configuration, verify the register units and stale-data response as well as the displayed number.

Test relevant mixer states and filling rates, and retain the final parameters and echo record. Where the signal is used for operational alarms, include the alarm thresholds in the test. Any separate protective function needs its own suitability review; a continuous level transmitter is not automatically an approved safety device.
