Product catalog summary

Overview

The RPMAG Electromagnetic Flowmeter is designed for measuring conductive fluids. It features a sensor pipe made of stainless steel 321 and is suitable for medium ambient temperatures ranging from -20°C to +75°C. The electronic housing is rated IP67 and includes an anti-condensation filter. The device includes two alarm relays for minimum and maximum flow detection.

Flange Sizes, Pressure Ratings, and Lining Materials

The flowmeter is available in various nominal diameters (DN) from DN10 to DN1000 with corresponding maximum pressure ratings and lining materials. The lining materials include PTFE (temperature range -40°C to +150°C) and Neoprene (temperature range -10°C to +80°C). Each DN size has specific flow ranges (in m3/h) and conforms to the UNI 1092-1 flange standard.

Examples:

  • DN10: 1.6 or 4.0 MPa pressure, PTFE lining, flow range 0.14 to 2.9 m3/h.
  • DN65: Options for Neoprene or PTFE lining, pressure ratings 1.6 or 4.0 MPa, flow range 5.8 to 120 m3/h.
  • DN250: Neoprene or PTFE lining, 1.0 or 1.6 MPa, flow range 85 to 1700 m3/h.
  • DN1000: Neoprene lining, 1.0 MPa, flow range 1450 to 28000 m3/h.

RPmag Electromagnetic Flowmeter-1

Flow measurement for conductive and chemically aggressive liquids Dn from 10 to 2000 mm Measurement accuracy: ± 0.2%; ± 0.5% Neoprene / PTFE coatings Power supply 85-265vAC; 12vDC; 24vDC lv AC Datalogger on USB pendrive Removable O-LED display module Remote control via Smartphone RPmag flowmeter is suitable for all of applications into “industrial process”. Various materials for lining are available as well as electrodes made of tantalum, hastelloy c, titanium. Most common communication systems such as Modbus, Hart and by means of an app for Android smartphone via Bluetooth. RPMAG has an integrated data logger for the recording of the measurements over time. It consist in an USB pen drive which is inserted behind the removable O-LED display VL701. The recorded data are stored into a TXT file which is compatible with Excel or other equivalent analisys software packages Flow rate range RPmag is able to process signals from fluids with flow rates of up to 10m/sin both directions (bidirectional meter).
