Glass-Tube, Stainless-Frame Purge Meters
These glass-tube meters have a rugged stainless-steel frame, available in 1½- inch and 3-inch scale lengths, and use a high-stability float for accurate, repeatable performance. Meters can be supplied with flow controllers and plastic bezels for flush mounting (not available with 1½-inch scale purge meter).

Arma-View® II Purge Meters
Purge meters for low-flow, high-temperature and high-pressure applications are available with optional 4-20mA transmitter and flow controller. An optional FM-approved hazardous location 4-20mA transmitter provides remote indication of flow rate. An optional purge-type flow controller keeps flow constant
regardless of pressure variations. It is offered in 316 stainless-steel construction, for inlet and outlet configurations. It can be assembled to the meter or as a standalone in the process line.

Armored Purge Meters
This armored purge meter operates over a 10:1 range. Scales are 1¼ inches long. The ½-inch meter has a GPH or SCFH scale; the ¾-inch meter has a GPM or SCFM scale. Each also has a percent scale. Construction of meter body is 316 stainless steel with Buna-N and TFE. Heavy-duty stainless-steel construction ensures proper operation to 100 bar (1500 psi) and 400°F. At no time is the glass scale tube exposed to the process fluid. A stainless-steel sheath encloses the O-ring-sealed glass tube. Flow switch available.

Electronic Transmitters
The Varea-Com™ transmitter provides linear 4-20 mA signal proportional to flow rate. The gasketed cast-aluminum case is compact, and rated NEMA® 4, and FM approved for use in hazardous areas. The transmitter is a smart, microprocessor-based, two-wire, low-power unit. Its patented sensor with microprocessor-controlled gain is capable of filling flow correction needs at the meter, providing accurate flow information remotely to external support systems. The patented magnetic sensor with automatic gain control enables a high dynamic-capture range without sacrificing accuracy.
