EX80 Insertion Magmeter

If you cannot find the part number in the documentation please provide detail. Specific to this item, it could include part number or application detail, (ex. 20 meters of cable, or 20 litres of volume)

The EX81 is an insertion electromagnetic flowmeter for use with conductive liquids in pipe sizes 1” to 3”. The EX82 Insertion Magmeter is for use with pipe sizes 4” to 8”. 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.

Fixed depth electromagnetic insertion flow meters

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 analogue output and display of rate and total, an FT420, pulse and 4-20mA output, can be used. For a 4-20mA analogue 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 require a special fitting, since they are 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.
