Abstract
A self-draining transmitter mount head includes a head body with a transmitter process coupling port in the head body, an impulse port in the head body, and an impulse passage coupled to the impulse port. An impulse drain passage is coupled between the pressure transmitter port and the impulse passage. The impulse drain passage is positioned at an angle to the impulse passage, and relative to a head installation angle that positions the impulse drain passage to drain away from the transmitter process coupling port through a range of head installation angles.

A self-draining transmitter mount head, comprising:
- a head body;
- a transmitter process coupling port in the head body;
- an impulse port in the head body;
- an impulse passage coupled to the impulse port;
- an impulse drain passage coupled between the transmitter process coupling port and the impulse passage, the impulse drain passage positioned at an angle to the impulse passage, and relative to a head installation angle that positions the impulse drain passage to drain away from the transmitter process coupling port through a range of head installation angles;
- a drain/vent port in the head body, the drain/vent port coupled to the impulse passage, wherein the impulse passage is coupled in a straight line between the drain/vent port and the impulse port;
- a removable drain/vent plug configured to seal the drain/vent port;
- and
- a drain/vent passage coupled between the drain/vent port and the impulse passage.
A self-draining transmitter mount head, comprising:
- a head body;
- a pair of differential transmitter process coupling ports in the head body;
- a pair of impulse ports in the head body;
- a pair of impulse passages, wherein a first of the impulse passages is coupled to a first of the impulse ports, and a second of the impulse passages is coupled to a second of the impulse ports;
- a pair of impulse drain passages, wherein a first impulse drain passage is coupled at an angle between the first differential transmitter process coupling port and the first impulse passage, and a second impulse drain passage is coupled at an angle between the second differential transmitter process coupling port and the second impulse passage;
- wherein the angled impulse drain passages are configured to drain away from the differential transmitter process coupling ports through a range of head installation angles
- a pair of drain/vent ports in the head body;
- a removable drain/vent plug configured to seal each drain/vent port;
- and
- a pair of drain/vent passages, a first drain/vent passage coupled between a first of the respective drain/vent ports and the first impulse passage, and a second drain/vent passage coupled between a second of the respective drain/vent ports and the second impulse passage;
- wherein each drain/vent passage is aligned with and coupled in a straight line to its respective impulse passage.
A method of installing a self-draining transmitter mount head, comprising:
- mounting the head in an orientation to allow internal draining of process fluid within the head away from a transmitter process coupling port when process flow stops;
- wherein mounting the head further comprises mounting within a first range of orientations to position angled drain passages in the head to drain process fluid out of the head;
- wherein mounting the head further comprises mounting to allow a second range of orientations to position angled drain/vent passages to drain away from the transmitter process coupling port through the second range of orientation angles 180 degrees opposite the mounted head orientation;
- and
- wherein the angled drain passages and the angled drain/vent passages drain to an impulse passage coupled in a straight line between impulse ports and drain/vent ports in the head.
