The EX81 is an insertion electromagnetic flowmeter for use with conductive liquids in pipe sizes 1 to 3 inches. The EX82, Insertion Magmeter, is for use with pipe sizes 4 to 10 inches. The EX83, Insertion Magmeter, is a stainless steel electromagnetic flowmeter designed for use with pipes 12 inches in diameter. With no moving parts, the insertion electromagnetic flowmeter is highly suitable for corrosive environments and for difficult applications such as those involving changing viscosities and pulsating flows. The insertion electromagnetic flowmeter is particularly recommended for metering the output of air-driven diaphragm pumps.


Designed for modularity and versatility, the EX80 series, insertion electromagnetic flowmeters, have a current-sinking pulse output, which can be combined with the appropriate transmitter or indicator depending on the application. For 4-20mA analog output and display of rate and total, an FT420, pulse and 4-20mA output, can be used. For a 4-20mA analog output only, the AO55, blind 4-20mA converter, can be mounted directly onto the meter. If the EX80 series, Insertion Magmeter, is being used with a programmable controller, the output signal can be fed direct with no other conditioning required.


The EX80 series, insertion electromagnetic flowmeters, requires a special fitting, since it is not depth-adjustable as are the EX100/200 series meters. Installation in the fitting ensures correct depth placement in the pipe. Fittings and sensors are available in PVC and stainless steel.


  • Low-flow performance and accuracy superior to any mechanical flow sensor
  • No moving parts to wear out
  • Dedicated fittings for simplicity
  • Retainer clip automatically sets correct depth
  • Meter extends only about 1/8 of pipe diameter, minimizing potential for clogging with debris
  • Simple pulse train output can be used with most signal processing modules, or sent directly to a PLC
  • Available for pipe sizes 1 to 12 inch, in 316 stainless and PVC
