1-1 Description
The Brooks ® MT3600, MT3601 and MT3602 armored flowmeters are
designed to be reliable and economical high flow rate purge meters with
10% full scale accuracy. These meters are especially useful for metering
coolants, pump seal fluids, lubricants under pressure, and opaque fluids.
The flow rate is measured by the movement of a tapered plug in a fixed
orifice. Indication is by an external tubular follower coupled magnetically to
an extension of the tapered plug. A certified explosion-proof/intrinsically
safe alarm is optional.
