GF Signet 5090 Sensor-Powered ProPoint Flow Monitor - Manual

Sensor Frequency = ___________________________ Hz
Technical note:
Sensor frequency MUST be greater than 45 Hz for full scale
needle defl ection.
3. Calculate the actual max. fl ow rate in your process line as follows:
Maximum fl ow rate = Sensor frequency (step 2) × A-Factor (Section 6)
Maximum Flow Rate = __________________________________
2. Calibration
The 5090/515 fl ow metering system utilizes the AC signal
amplitude from the 515 sensor to drive the 5090 meter.
The front panel meter movement adjustment (SPAN) is easily
accessed under the removable front window for simple calibration.
A dial kit with six dial ranges, assorted fl ow unit/multiplier decals,
and dial installation instructions is included for your convenience.

4. Install the appropriate dial face and fl ow unit/multiplier decal
for the maximum fl ow rate (Step 3). Refer to dial installation
instructions included with dial kit.
The dial kit includes the following:
Example: A fl ow system's maximum fl ow rate is 18.3 GPM.
The proper dial and fl ow unit/multiplier decal for this fl ow system is:
0 - 2 dial + GPM × 10 decal.
5. Disconnect frequency counter.
Access and adjust the "SPAN" potentiometer to match the
calculated maximum fl ow rate from Step 3.
After adjustment, calibration is complete.

Technical Notes:
•
Remove terminal block for easy wiring (Fig. 1)
• Maintain cable shield through cable splice.
• Route sensor cable away from AC power lines.
• Use 2-conductor shielded cable for sensor cable extension up
to 61 m (200 ft).

Procedure
1. Induce the maximum (stable) fl ow rate in your process line.
2. Using the frequency counter, monitor and record the 515
sensor frequency output:
Equipment Required
• Frequency
counter
• Signet 515 Sensor installed in process line
• Standard and phillips head screwdriver
