Installation
For optimum performance, install the flow meter in one of the configurations shown below. The following items and
conditions should be considered:
Line and Bypass Valves: These valves allow filter cleaning or flow meter removal without completely shutting the system
down and draining the lines. They also allow system start up under conditions which could damage the meter; such as:
air in the lines, high temperature materials, or initial line surges.
Filtration: Clearances between the flow meter piston and cylinder wall are typically 0.0002” to 0.0004”. Any dirt
present in the system can jam or damage the unit. A 10 micron filter (such as a Max 381 Series stainless steel unit) is
generally recommended, although materials with very high viscosities may require a coarser filter. For bidirectional flow
applications, use a filter on each side of the flow meter. Materials with fibrous or non abrasive particulate matter may
have to be run without filters. Follow the recommendation of your Max Sales Engineer or consult our Technical Service
Department.
Inlet and Outlet Ports: Use the “IN” port as the inlet for the most predominant flow direction. Install the flow meter on
the discharge side of the pump whenever possible. Excessive vibration at the meter should be avoided.
High Temperatures: Use the “Vertical Installation” drawing. This minimizes heat transfer by convection from the flow
meter to the transmitter. The transmitter is the most heat sensitive element in the system and the transmitter manual
should be consulted for specific limits. An optional fluid heater block can be used on the flow meter to keep it at
operating temperature during standby conditions. For substances that are solid at room temperature, the block may be
required to keep the material molten and flowing through the meter.
Clean Plumbing: Before installing the flow meter, clean the inside of the pipe line with compressed air or steam
(especially when using new pipe). Don’t use water, steam, or compressed air on the meter itself!
