GF Signet 2551 Magmeter Flow Sensor - Display - Manual (Page 12)

12 2551 Magmeter
7.3 Calibration Data: K-Factors
7.2 Bi-Directional Flow
• The 2551 magmeter is designed to measure bi-directional À ow.
• The forward À ow direction is indicated by the directional arrow molded into the side of the 2551 sensor.
• The conduit ports are assembled at the factory to point UPSTREAM. They may be reversed by
disassembling the components of the magmeter and reassembling.
Flow Rate Display: The "+" sign is suppressed during forward À ow.
"-123.45 GPM" during reverse À ow.
Totalizer Display: The totalizer will count during forward À ow conditions only.
During reverse À ow the totalizer will not increment.
Relay Outputs: May be set to detect reverse À ow: "Low Setpoint at -25 GPM."
4 to 20 mA output: May be scaled to span any À ow range:
For example: "4 to 20 mA = -100 GPM to +100 GPM"
Frequency output, Frequency ÷ 10 output: Reverse À ow is processed same as forward À ow in the frequency output magmeters.
Digital (S 3 L) output: Reverse À ow results in 0 À ow rate output.
