Installation
2-2 P/N M/97-520
• Provide a continuous product stream flow rate of 0.5 to 20 GPM
that produces a pressure drop of less than 25 psi.
NOTE: The estimated resistance to flow of a 1, 1.5, or 2 inch TT100 is
equivalent to that of an average 3 inch globe valve.
• Provide a straight pipe leading into the viscometer that is at least
ten times the pipe diameter in length.
• Know the product stream’s rheology and how it responds to other
factors occurring in the process such as temperature, pH, pressure,
etc. Control or monitoring of the product stream’s temperature may
be required.
• Power: Single phase, 115 or 230 VAC 50 or 60 Hz
• For NEMA 7 applications, the customer must provide a 600 VAC,
18 Gauge, two conductor with ground viscometer power cable
between the Motor Control Enclosure and the viscometer motor
which must conform to local electrical codes.
• Flushing connection: 1/8 inch-27 NPT thread in either endcap
5 - 10 GPM of flushing fluid at 40 - 90 psig.
• If equipped, double mechanical seals require clear barrier fluid
under pressure at 20 psi above maximum process pressure
connected to a 1/8 inch standard pipe thread connection in the drive
endcap. No flow is required, but venting of air from the seal is
required to avoid premature seal wear.
• If the viscometer is to be cleaned in place, isolation valves, flow
boosters, or other auxiliary items may be required.
