ERDCO ArmorFlo 3600


The Armor-Flobody housing has a variable internal volume which enlarges from the inlet to the outlet. The primary sensor is a tempered alloy vane with one end affixed to the apex of the meter housing. As the flow rate changes, the vane is flexed in direct proportion. A PTFE encapsulated magnet links the vane position with the
pointer in the indicator housing and the signal output/switch circuit. All adjustments and electrical connections are accessible from the front of the meter housing.

Armor-Flometers with integral transmitters provide an ideal combination – a local mechanical flow rate indicator independent of electrical supply with a 4-20 mA two wire loop powered signal output. The output signal is linear within the middle 80% of the range. A response curve is furnished with each flowmeter. Simple design, rugged construction and good value make this the ideal utility fluid flowmeter.
