1. Compatible Sensor Wiring

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).

2. Calibration

The 5090/515 fl ow metering system utilizes the AC signal
amplitude from the 515 sensor to drive the 5090 meter.

English

Fig. 1

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.

Equipment Required

• Frequency counter

• Signet 515 Sensor installed in process line

• Standard and phillips head screwdriver

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:

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:

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 = __________________________________

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.

5. Maintenance

Front View

Panel cutout

Never wipe the front window with static retentive cloths such as wool or polyester which may induce a static charge. If a static charge
develops on the window, the indication needle may appear erratic or non-functional. When this occurs, clean the front window with an
anti-static cloth, or a soft cotton cloth and anti-static spray or a mild liquid soap solution to remove the static charge.

Clean the instrument case and front panel with a soft cotton cloth dampened with a mild liquid soap solution.
