Chapter 1. Description
1-1. General
The pressure detector (meter body) accepts a process pressure with its pressure receiver
element and converts the process pressure into a torque with its torque tube. The torque is
applied to a pneumatic transmitter (Model KKP or KFKB) or a pneumatic controller (Model
KFKB).
Some models of detectors have a flange incorporated with a diaphragm for connection to the
process.

The process pressure is fed through the flange or cover (and via the seal liquid in the case of a
remote-sealed type) to the pressure receiver element which exercises a rotational force on the
torque arm. The torque arm drives the torque tube through which a torque force representing
the process pressure is applied to the beam of the instrument.
The reference-pressure chamber of the absolute-pressure detector (meter body) is kept
vacuum.

Chapter 3. Installation
3-1. General
The meter body (detector), together with the instrument (transmitter) coupled to it, can be
installed on a 50-mm pipe stanchion by using the accessory bracket and U-shape bolt.
Model 61/62 meter body can be installed simply by fixing its flange to the process.
3-2. Bracket and bolts
The bracket and bolts for installation are supplied accompanying the meter body.
3-3. Place of installation
When selecting a place of installation for the instrument, take into consideration the matters
related to instrument inspection, maintenance, longevity, and operation safety as follows:
(1) Select a place where temperature change is small (within the limits of –30 °C to +80 °C).
Avoid a place where the instrument is exposed to high temperature by radiation from a
source of heat.
When water is measured, pay attention to freezing which may cause damage to the meter
body. Provide appropriate means to guard against freezing.
(2) Select a place where is reasonably free from humidity and vibration.
(3) Be sure to provide spaces for inserting a screwdriver for adjustment and span change.
Fig. 3-1.

3-4. Installation method
3-4-1. Installation of regular-type meter body
The meter body, together with the transmitter coupled to it, can be installed in either one of
the following methods:
• Pipe stanchion mount
• Process pipe mount
In either case, fix the meter body to a 50-mm vertical or horizontal pipe using the mounting
bracket and U-shape bolt. Fix the pipe securely to a foundation so that the pipe does not sway.
(See Fig. 3-3.)
To install the meter body on a process pipe line, prepare brackets for mounting the 50-mm
pipe to the process pipe. (See Fig. 3-2.)
When installing a remote-sealed type of meter body, exercise care not to sharply bend or twist
the capillary tube and not to damage the diaphragm.
Fig. 3-2. Example of line mount bracket
Note: When installing the transmitter (meter body) on a 50-mm pipe, note that the order of
mountings (transmitter, bracket, and 50-mm pipe) differs depending on the mounting
direction.
Fig. 3-3. Installation examples
6
3-4-2. Installation of remote-sealed diaphragm type meter body
This type of meter body can be fixed to a pipe stanchion in the same manner as in the case of
the regular type of meter body. For connection to the process, proceed as follows:
(1) Connect the tapping flange to the process flange with the bolts and gasket. Evenly tighten
the bolts to prevent leak. Lay the capillary tube so that it is less subjected to temperature
change and fix it so that it does not move.
It is recommendable to install the transmitter at a location lower than the flange.
(2) If the zero point shift has been caused by the head pressure of the seal liquid due to
the difference in height between the center of the flange and the center of the pressure
receiver, adjust zero by means of the ZERO control (or ELEVATION or SUPPRESSION
control). The specific-gravity of the seal liquid is 0. 935 at 20 °C (For temperature
compensation, use a factor of 0.001/°C).
(3) For installation of the button diaphragm, refer to its dimension drawing.
When the installed button diaphragm is required to be pulled out, set the collar available
as an option to the groove at the rear end of the element (capillary tube side) and retract
the screw.

3-5. Pressure piping
3-5-1.
The pressure piping method (tapping pressure connection method) for the meter body
(transmitted) differs by installation position of the meter body, by the type of the process pipe,
and other conditions of measurement.
3-5-2.
Typical examples of pressure piping methods are shown in Fig. 3-4. For piping, observe the
following instructions.
(1) Install a tee joint in the pressure tap line.
(2) Install a stop valve between the pressure tap point and the tee joint.
(3) For the pressure connection piping from the tap point of a horizontal process pipe to
the meter body, provide a gradient so that drain is returned through the tap point to the
process pipe.
Note: To measure a high pressure, pay attention to the types of joints, and pipe
(4) For pressure piping from the process pipe to the transmitter, use an appropriate type
(appropriate schedule number and nominal thickness) of pipes depending on the process
pressure and other measuring conditions. An example is a 1/2 inch Schedule 80 steel pipe.
Copper pipes are used in general for measurement of water or steam pressures.
dimensions and materials.
3-5-3. Auxiliary devices
(1) Oil seal and air purge
When it is undesirable to lead directly the measured pressure medium (fluid with
suspension, highly viscous fluid, or corrosive fluid) to the pressure transmitter, use liquid
seal or air purge.
Various liquid seal and air purge methods are possible. For details, please consult an Azbil
Corp. representative.
(2) Pulsation damping
When the process pressure pulsates or otherwise varies abnormally rapidly, install a
restriction valve in the pressure piping in order to smooth out such rapid pressure change.

3-6. Elevation and suppression
3-6-1. Definitions of elevation and suppression
The terms “elevation” and “suppression” as used in this publication are defined as follows:
Elevation: Synonymous with “suppressed zero range”
An input range whose low end value is higher than zero.
For example, a range of 20 to 100.
Suppression: Synonymous with “elevated zero range”
An input range whose low end value is lower than zero.
For example, a range of –20 to 0.
3-6-2. Setting of elevation/suppression
For setting of elevation/suppression, refer to Section “CALIBRATION AND ADJUSTMENT”
of Operator’s Manual for Pneumatic Transmitter OM2-5220-0000.
When calculating the head pressure of the seal liquid of Model 71/72/73/74/75/76, multiply
the level difference between the center of diaphragm and the center of detector by the specificgravity of seal liquid (0.935*) and take the product value for the elevation.
See 3-4-2 (2)
*
Fig. 3-5.
Note: Elevation alone is applicable to Model 25/26/27/28. To other models, suppression is
applicable for vacuum pressures.

Chapter 4. Operation method
The meter body, together with the transmitter coupled to it, starts operating as the air supply
and process input are fed to it. (It is recommendable to check the operation of the transmitter
before starting the running operation.)
(1) Measurement of liquid or gas pressure (Except vacuum pressure process)
Close the block valve, open the bleed valve, and then open the stop valve in order to blow
the pressure piping to eliminate foreign matter from inside the piping. Next, close the
bleed valve, wait until the pressure piping is cooled off if process temperature is high, and
then open the block valve to lead process liquid or gas to the meter body. (No bleed is
required for vacuum pressure processes.)
(2) Measurement of steam pressure
The operating procedure is the same as that for liquid or gas pressure measurement of (1),
except the following: After blowing the pressure piping to eliminate foreign matter and
closing the bleed valve, condense steam so that the pressure piping and siphon are filled
with water, and then open the block valve.
(3) Correction for Installation height of transmitter
When a liquid pressure is measured or when there is condensed steam in the pressure
piping, correction should be made, as required, for the head pressure which depends
on the height of installation of the transmitter. (This will be required especially when
measuring low pressures.) For this correction, shift the zero point of the transmitter by
an amount corresponding to the differential height between pressure tapping point and
transmitter installation position multiplied by the specific gravity of the liquid. (Elevation)
(4) Zero point check
When the instrument has become the measuring state, check and adjust the zero point
with the receiver connected to the transmitter.
11
Chapter 5. Inspection and maintenance
For routine inspection and maintenance, pay attention to the following:
5-1. Check for leak from piping
Check that there is no leak in the piping from the pressure tap points to the meter body. If any
loose connections are found, tighten them securely.
5-2. Blow and cleaning of meter body and piping
To maintain constantly the instrument at its best performances meeting its specification
accuracy, keep clean the meter body and its piping. If sediment or other foreign matters are
entrapped in the pressure chambers of the meter body, measuring errors may be caused. To
blow and clean the meter body and piping, proceed as mentioned in the following referring to
3-5. Pressure piping of Chapter 3. Installation.
1. Close the stop valve.
2. With the block valve kept open, rapidly open the bleed valve.
3. Close the bleed valve and open the stop valve.
For a vacuum pressure process, blow the piping only when the process is at a positive pressure.
No blowing is necessary for the remote-sealed diaphragm type of meter bodies.
5-3. Notes for use in freesing season
When the transmitter used for measurement of water or other freezable liquid is paused
in a freezing season or area, loosen the bleed valve and drain out liquid from the pressure
chambers to prevent freezing.
