Description
The Brooks® MT3600, MT3601 and MT3602 armored
flowmeters are designed to be reliable and economical
high flow rate purge meters with 10% 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.

Table 1 Capacities and Pressure Drop
1. All air flows given are at 14.7 psia and 70°F.
2. 1" and 1-1/2" meters not recommended for gas service, due to
stability of float.
3. Minimum operating pressure (downstream) on gas service is 35
psig for 1/2" size. Consult factory for other conditions.
