This versatile capacity makes it an ideal choice for industries where flow rates can vary significantly, ensuring it caters to a wide array of applications.
This meter thrives under pressure, with a capability to endure pressures of up to 185 bar (2683 psi). Even in extreme temperature conditions, ranging from a bone-chilling -50°C (-58°F) to a sweltering +210°C (410°F), the RHM 20 maintains its precision and functionality.
Features:
- Range: 1 kg/min up to 480 kg/min
- Pressure: up to 400 bar (5801 psi)
- Temperature: -50°C (-58°F) up to +210°C (410°F)
- Accuracy: 0.1 % of rate
- Materials: SS 316L / SS 316Ti, Alloy C22 – 2.4602, Tantalum – UNS R05200, Super Duplex – 1.4410
- Process Connection: 1″ up to 2″
- Suitable for fiscal / custody transfer applications
- Available in all exotic materials
Its remarkable accuracy, quantified at 0.1% of the rate, ensures that the data it provides is consistently reliable. Operators can rely on its measurements with confidence, minimising errors in their processes. The RHM 20’s construction is engineered for durability, crafted from high-quality materials, including SS 316L, SS 316Ti, Alloy C22 – 2.4602, Tantalum – UNS R05200, and Super Duplex – 1.4410. This diverse material selection ensures compatibility with various liquids and safeguards against corrosion, even in the harshest environments. Process connections ranging from 1″ to 2″ enhance its adaptability, allowing for seamless integration into existing systems and setups. The Rheonik RHM 20 Coriolis Mass Meter’s blend of reliability, precision, and affordability sets it apart, making it a cost-effective investment for industries seeking unparalleled flow measurement performance.

* At Qnom pressure drop across a parallel tube sensor will be approximately 1 bar (14 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.
