1. Remove the MVS205 sensor from the
shipping box.
2. Find a suitable location for the MVS205
sensor. Check all clearances when choosing
an installation site. Provide adequate
clearance for wiring and service.
3. The Coplanar™ flange on the bottom of the
MVS205 Sensor body allows mounting on a
pipestand, wall, panel, or to the flange taps of
an integral orifice assembly or manifold valve.
The MVS205 can be mounted to a panel or
pipe (see Figure 3, Figure 4, and Figure 5) with
the optional bracket kit, which includes an L-
shaped bracket and a pipe clamp. The bracket
kit attaches to the coplanar flange at the
pressure connector.

4. The process pressure inputs are piped to the
¼-18 NPT connections on the bottom of the
MVS205 or to an intervening manifold valve.
®
You also mount the MVS205 directly to flange
taps using a manifold valve or an integral
orifice assembly (not shown).
5. Use the field wiring entries to bring the wiring
into the MVS sensor electronics head. Metal
pipe plugs must remain in place on unused
wiring entries to maintain flame-proof
integrity of enclosure.
Cable Connection
The cable entry device shall be certified in
type of explosion protection flame-proof
enclosure "d", suitable for the conditions of
use and correctly installed. For ambient
temperatures over 70°C, use cables and cable
glands suitable for at least 90°C.
