The specifications provided are detailed technical information for a flow sensor model, likely the Rheonik RHM series. Here is a summary of the key points:

Flow Specifications

  • Nominal Flow (Qnom): 0.6 kg/min (1.32 lb/min)
  • Maximum Flow (Qmax): 1.2 kg/min (2.65 lb/min)
  • Typical Minimum Flow (Qmin): 0.002 kg/min (0.004 lb/min)
  • For serial configurations, flow rates (Qmax, Qnom, Qmin) are 50% of those for the parallel/dual path version.

Temperature and Pressure Ratings

  • Fluid Temperature Range: -196°C to +210°C (-320°F to +410°F)
    • Note: Refer to the transmitter datasheet for integral transmitter versions.
  • Ambient Temperature: -50°C to +80°C (-60°F to +180°F), with a high-temperature version up to +210°C (+410°F).
  • Pressure Rating: Up to 1481 bar (21480 psi), material-dependent.

Electrical Connections

  • Sensor without Integral Transmitter:
    • Standard entry: M20 x 1.5 for JM and SM terminal boxes.
    • Optional entries include ½” NPT, M25 x 1.5 (only SM), or ¾” NPT (only SM).
    • PM terminal box version: M16 x 1.5 standard.
    • Maximum cable length: 100 m (330 ft) to remote RHE transmitter.

Enclosure and Wetted Material Options

  • Enclosure Material: Stainless steel 304 (standard), SS 316 (optional), coated aluminum or SS 316 for the terminal box.
  • Enclosure Type: IP66, NEMA 4 (standard); optional IP66/67, NEMA 4X.
  • Wetted Materials: Various stainless steel options (SS 316L, SS 316Ti) and specialized alloys (SuperDuplex, Alloy C22).

Process Connections and Approvals

  • Process Connections: Customizable to various fittings (AnyPipeFit Commitment).
  • Pressure Compliance: Follows PED 2014/68/EU Article 4, Section 3.
  • Certifications: ATEX, IECEx (Zones 0, 1, 2), North American approvals, ABS.

Testing, Inspection, and Additional Services

  • Testing: Hydro tested and calibrated with traceable certification; customized calibration/testing available.
  • Additional Services: Project documentation, QA, origin certificates, functional testing, and more.
  • Customization Options: Available for machine integration and specific project needs.

Important Notes

  • Pressure Drop: Approx. 2 bar (29 psi) for H2O at Qnom in parallel tube sensors; will increase with higher flow rates or in high-pressure models.
  • Accuracy at Low Flow: Qmin represents the recommended minimum for accurate measurements; flows below Qmin can be measured but with increased uncertainty (>1% rate).

This data provides critical specifications needed for selecting or integrating the flow sensor in various operational environments and engineering projects.
