Section 2 Installation
Recommended installation for Models MT3809 and MT3810 is as follows:
a. Carefully remove the covers from each end of the flowmeter. The float
may be fixed to avoid damage during transport. These plugs must be
removed before use.
b. Install the flowmeter with the inlet at the bottom and the outlet at the top.
c. When installing the flowmeter in the process line, follow accepted plumbing
practices for flanged meters (see Section 2-5-1 for lined meters).
d. Install the flowmeter within 5° of true vertical. Use of a level is
recommended to determine the proper alignment.
e. When the process temperature is 300°C / 570°F or above insulation is
required on the meter body and flanges. The insulation is installed
between the indicator housing and the body and flanges. Do not wrap the
indicator with insulation. Recommended insulation materials are calcium
silicate, cellular glass or mineral wool.
