Mounting; Threaded Flange Mounting; Welded Flange Mounting - MTS Systems Level Plus Operation And Installation Manual

Mounting

The method of mounting the transmitter is dependent on the vessel or tank in which it is being used, and what type of transmitter is being
mounted. There are three typical methods for mounting; threaded flange mounting, welded flange mounting, and sanitary Tri-Clamp mounting.

THREADED FLANGE MOUNTING

In most applications, the Model MR transmitter can be mounted
directly to the tank or flange via a NPT threaded fitting, assuming
there is a proper threaded connection available. If the float will not fit
through the flange opening when the flange is removed, there must
be some alternative means to mount the float on the transmitter from
inside the vessel; this may require an access port nearby the entry
point of the transmitter as shown in Figure 6.

WELDED FLANGE MOUNTING

The Model MR transmitter can also be mounted to a tank flange as
shown in Figure 7. First, install float(s) onto the transmitter. Second,
install the float retaining hardware on the tip of the transmitter. To
complete the installation, mount the transmitter, flange and float(s)
as a unit in to the tank.
