10 Micro Motion 7829 Viscomaster
®
and Viscomaster Dynamic
™
Viscosity Meters
Installation
2.4 Standard installations
2.4.1 Overview
To overcome the need for in situ calibration for every installation, three standard installations are
proposed. If an installation conforms to one of these standards, the factory calibration of the 7829
Viscomaster
®
/ Viscomaster Dynamic
™
viscosity meter is valid, and in-situ calibration unnecessary.
The three installations are summarized in Table 2-1.
Note: Higher flow rate installations (up to 100 m
3
/hr) can be accommodated. Contact Micro Motion
for details.

VAF VISCOSENSE Retrofit Flow-through chamber
Description
Viscomaster tines project into
adapter kit with 2½“ Schedule
40 boundary.
Viscomaster tines are
contained in a side pocket off
the main flow, recessed by
25.4 mm (1 inch).
Viscomaster tines are contained in
a flow-through chamber in which
fluid is circulated from the main
flow.
