Transmitter Mounting, Direct Mount Head with Valves
It is not necessary to retract the Annubar when direct mounting a
transmitter with valves.
1. Place Teflon
®
(PTFE) O-rings into grooves on the face of head.
2. Align the high side of the transmitter to the high side of the sensor
(“Hi” is stamped on the side of the head) and install.
3. Tighten the nuts in a cross pattern to 400 in•lb (45 N•m).
Transmitter Mounting, Direct Mount Head without Valves
1. Place Teflon (PTFE) O-rings into grooves on the face of head.
2. Orient the equalizer valve(s) so they are easily accessible. Install a
manifold with the smooth face mating to the face of the head.
Tighten in cross pattern to a torque of 400 in•lb (45 N•m).
3. Place Teflon (PTFE) O-rings into grooves on the face of the
manifold.
4. Align the high side of the transmitter to the high side of the sensor
(“Hi” is stamped on the side of the head) and install.
5. Tighten the nuts in a cross pattern to 400 in•lb (45 N•m).
Transmitter Mounting with Remote Mount Head
Temperatures in excess of 250 °F (121 °C)at the electronics will
damage the transmitter. Remote mounted electronics are connected to
the sensor by means of impulse piping, which allows service flow
temperatures to decrease to a point where the electronics are no
longer vulnerable.
Different impulse piping arrangements are used depending on the
process fluid and must be rated for continuous operation at the
pipeline design pressure and temperature. A minimum of
1
/
2
in. (12
mm) outer diameter stainless steel tubing with a wall thickness of at
least 0.035 in. (1 mm) is recommended. Threaded pipe fittings are not
recommended because they create voids where air can become
entrapped and create leakage points.
