FMU30 sourcing: two sensor sizes with a mechanical interface to verify

The Endress+Hauser Prosonic FMU30 is a two-wire ultrasonic transmitter for non-contact level measurement. It is used in sewage treatment, process-water vessels, loading systems, storage tanks and buffer tanks. Its 4–20 mA output supports conventional analogue loops; specify the required interface explicitly when replacing another transmitter.

The real engineering question: will the echo remain usable?

FMU30 has two sensor sizes with different liquid ranges, solid ranges and blind zones. A quote based only on the largest family range can hide a mismatch. Confirm the configured sensor, thread and usable measuring span before ordering. Foam, strong surface turbulence, heavy dust, filling curtains, vapour, temperature gradients, vessel internals and poor nozzle position can weaken or multiply echoes. The actual usable range therefore depends on the measuring conditions. This is why an honest quotation should begin with the medium and geometry rather than only the words “0–8 metres.”

The blocking distance is 0.25 m for the 1½-inch sensor and 0.35 m for the 2-inch sensor. Product must not enter this near-sensor zone at maximum level. A replacement mounted too low may be commercially correct yet operationally unsuitable.

FMU30 buying questions

What is the maximum range of an E+H FMU30?

The published maximum is 5 m for liquids and 2 m for solids with the 1½-inch sensor, or 8 m for liquids and 3.5 m for solids with the 2-inch sensor. Real performance depends on surface and installation conditions, so the application should be reviewed before treating that number as a guaranteed working range.

Can FMU30 measure without touching the product?

Yes. Ultrasonic pulses measure distance to the surface without a probe in the medium. Check foam, turbulence, vapour and the sensor’s blocking distance when evaluating the installation.

What information is needed for an FMU30 quotation?

Provide the complete order code, medium, measuring distance, nozzle and tank geometry, temperature, pressure, approvals, quantity and delivery destination. For this enquiry, use FMU30 FMU30-AAHEAAGGF.
