Rheonik RHM 04 Small Coriolis Mass Flow Meter < 18 kg/min

ABLE Instruments are Rheonik’s Exclusive Representative for Sales and Service in the UK and Ireland, including the RHM 04 Small Coriolis Mass Flow Meter. The RHM 04 is a game-changer in the world of precision applications, offering a fast response solution for batching, dispensing, and filling tasks. This remarkable meter is engineered to provide unparalleled performance in processes where Coriolis meter use was previously impractical.

With a remarkable flow range from 0.05 kg/min to 18 kg/min, the RHM 04 Coriolis Mass Flow Sensor caters to a wide spectrum of applications, ensuring it meets the demands of various industries, from pharmaceuticals to petrochemicals.

What truly sets the Rheonik RHM 04 Flow Sensor apart is its extraordinary capacity to withstand extreme pressures, reaching up to an astonishing 1401 bar (20319 psi). This high-pressure capability opens doors to applications that were once considered beyond the reach of Coriolis meters.


  • Range: 0.05 kg/min up to 18 kg/min
  • Pressure: up to 1401 bar (20319 psi)
  • Temperature: -196°C (-321°F) up to +210°C (410°F)
  • Accuracy: 0.1 % of rate

  • Available in all exotic materials

Temperature extremes pose no challenge for the RHM 04 Flow Sensor. It operates flawlessly in conditions ranging from a frigid -196°C (-321°F) to a scorching +210°C (410°F), maintaining its accuracy and precision. Speaking of precision, the RHM 04 boasts an accuracy rate of 0.1%, ensuring that the data it provides is consistently reliable. This level of accuracy is essential in industries where even the slightest deviation can have significant consequences. The Rheonik RHM 04 is constructed with a selection of robust materials, including SS316L, SS316Ti, Super Duplex – 1.4410, and Sandvik HP160, making it compatible with a wide range of liquids and resistant to corrosion. The meter’s adaptability is further enhanced by its process connections, ranging from ¼” to 1″, allowing for seamless integration into existing systems and setups.

In summary, the RHM 04 Coriolis Mass Flow Meter is a groundbreaking solution for precision applications, offering rapid response, high-pressure capabilities, and a wide operating temperature range. Its impressive performance parameters make it a top choice for industries seeking accuracy and reliability in their batching, dispensing, and filling processes.

* At Qnom pressure drop across a parallel tube sensor will be approximately 1.6 bar (23.2 psi) for H₂0. Sensors can be operated at higher flow rates up to Qmax but pressure drop will be higher. Typical Minimum Flow Qmin is the recommended lowest flow rate for an accurate measurement. Sensors will measure flow rates lower than Qmin but uncertainty will increase beyond 1 % of rate.

The flow rate specifications above relate to standard pressure, parallel tube, manifold sensor versions. Models with higher pressure ratings have increased wall thickness and will have higher pressure drops.
