3.2.2.3 Mount with a capillary viscosity retrofit kit
The capillary viscosity retrofit kit provides a simple, direct replacement for existing capillary meters.
Typically, capillary meters operate with their own measurement chamber that attaches to the HFVM. No
pipework changes are necessary.
CAUTION
Observe all corporate and government safety regulations. Wear protective clothing,
safety glasses, and gloves to prevent burns and the absorption of hot oil
Prerequisites
Verify the following conditions:
Temperature –50 °C to 200 °C (–58 °F to 392 °F)
Flow
40 to 330 l/min
2.5 to 20 m
3
/hr
11 to 87 US gal/min
Viscosity Up to 100 cSt
Pressure As defined by process flanges
Calibration

2.5 in Schedule 40
Procedure
1. Check that the isolation valves are fully closed.
2. Remove insulation and allow the equipment to cool to a safe level.
Cooling reduces retained pressure.
3. If you have a drain or a pressure-relieving valve, depressurize the system.
4. Slacken the lock nut 1 ½ to 2 turns so that you can rock the sensor.
If necessary, use your hand to jolt the meter loose from the amplifier housing. This breaks the seal between
the sensor and the chamber retrofit kit. Do not slacken the lock nut further unless the seal is broken and the
sensor is obviously loose in the fitting.
NOTE!
If the system is still pressurized, you will be able to lift and hold the meter against the retaining
nut. Rocking and alternately pushing the sensor in and out of the pocket within the limits
allowed by the slackened nut breaks the seal and allows oil under pressure to seep past the
lock nut. If this leakage is excessive, re-tighten the lock nut and take further action to
depressurize the system.
5.
CAUTION
Keep all parts of your body away from the direction in which you will remove the
sensor. Pressure caused by a valve failure or a poorly placed lock nut can eject the
instrument from the flow chamber and cause serious injury.
Remove the lock nut if you can rock the meter in the flow chamber, and there is no serious or continuous
escape of oil.
6. Retrofit the meter per the following diagram.
