Models FT-1, PFT-2, FT-2XP, RST, & RST-6P

OVERVIEW

The Models FT-1, PFT-2, FT-2XP, RST and RST-6P transmitters are designed for use with Badger Meter magnetic drive meters. Mounted on the meter, the transmitter can be wired to other pulse-operated instruments that have scaling capabilities and that can receive pulses from a reed switch.

The FT-2XP transmitter is identical to the PFT-2 except for the housing. The PFT-2 transmitter has a glass-filled plastic housing and a NEMA 4X rating. The FT-2XP transmitter housing is cast bronze and is CSA listed for use in hazardous locations. The FT-1 is offered only on the OP meter and is mounted in the OP housing directly with a stainless steel cover.

These transmitters do not have gear trains. The reed switch is directly coupled to the drive magnet within the meter.

OPERATION

The flow of liquid through the meter is measured by a disc or piston metering element. The motion of the metering element is transferred to a magnet which is located within the meter housing.

As the magnet turns, it causes the reed switch to open and close. Contact closures from the switch are transmitted to a remote batch controller or counter.

APPLICATIONS

These transmitters are normally connected to metering systems that have scaling capabilities and that can accept a reed switch pulse.

Typical applications would be chemical batching systems, chemical additive systems and other applications that require totalizing meter flow and monitoring rate of flow of fluid passing through the flow meter.

See the chart to the right for the average number of output pulses per US gallon for your particular meter. For more precise calculations, use the information on the transmitter data plate when figuring scale factors.

Example:

Compute the scale factor for a 1" OP meter. You want to measure the flow to the nearest 0.1 US gallon.
