VCS - Viscomaster™ 13
3.2.1 Prepare the installation
Before you can install the meter and fit the thermal insulation, verify that the system is stable and leak free.
1. Fit a blanking compression nut to the meter mounting, pressurize, and flush the system.
2. Isolate the system, depressurize, and remove the blanking compression nut.
Adjustment of and work on the Meter may only be done by skilled labor.
Observe local instructions and safety regulation.
3.2.2 Mount the meter
There are three (plus one) ways to mount the meter.

3.2.2.1 Mount with a flow-through chamber
Flow-through chambers are manufactured by Aquametro Oil & Marine, and are available with either of the
following:
Welded ends or compression fittings that connect into the process pipelines
1- inch, 2-inch, or 3-inch inlet and outlet pipes
IMPORTANT
Do not alter the length of the inlet and outlet pipes. Pipe alterations can adversely
affect the fitting, temperature response and stability.
Prerequisites
Verify the following conditions:
Flow
• 5–40 l/min for 2-inch Schedule 40 calibration bore section
(1.5 - 10.5 gal/min)
• 5–300 l/min for 3-inch Schedule 80 calibration bore section
(1.5 – 80 gal/min)
Viscosity 0.5 to 100 cSt
Temperature –50 °C to 200 °C (–58 °F to 392 °F)
–40 °C to 200 °C (–40 °F to 392 °F) in hazardous areas
Pressure 70 bar @ 204 °C, subject to process connections
IMPORTANT
To ensure that the fluid within the pocket is refreshed in a timely manner, verify that flow
velocity at the pipe wall and fluid viscosity are within the limits described in this table.
The thermal mass of the flanges may affect the response time of the meter to
temperature changes.
