SAFETY INSTRUCTIONS
1. Do not remove from pressurized lines.
2. Do not exceed maximum temperature/pressure specifi cations.
3. Wear safety goggles or faceshield during installation/service.
4. Do not alter product construction.
5. Apply sealant or PTFE tape to sensor threads, inspecting threads to ensure integrity.
Do not install a sensor with damaged threads.
Pipe fi ttings MUST be installed by a certifi ed welder only. Signet will not assume liability of any kind for improper fi tting
installations.
2517 Hot-Tap sensor specifi cations and limitations depend on the lowest maximum rating of the components associated with
the system. a ball valve, a component of the system, is rated at a maximum 100 psi @ 175°F, limiting the entire system's
maximum pressure/temperature rating to 100 psi @ 175°F. All higher maximum specifi cations MUST yield to the component
with the lowest maximum specifi cation.
Maximum Operating Pressure/Temperature:
• 17 bar (250 psi) @ 82°C (180°F) with standard FPM sensor fi tting O-rings.
• 17 bar (250 psi) @ 100°C ( 212°F) with optional EPR sensor fi tting O-rings.

• Use 2-conductor shielded cable for cable extensions up to 300m (1000 ft.)
• Maintain cable shield through splice.
5. Installation
The following items are required to properly install Signet 2217 Sensors.
5.1 Hardware, Standard Sensor
• Female pipe fi tting (weld-on or saddle) with 1.5 in. NPT or ISO 7/1-Rc 1.5 threads
• 32 mm (1.25 in.) diameter drill
• Pipe thread sealant
• Tape measure
5.2 Hardware, Hot-Tap Sensor
The Hot-Tap sensor requires all the standard sensor items plus:
• Hot-Tap drilling machine (e.g., Mueller drilling machine or equivalent)
• Female ball or gate valve (full port only) with 1.5 in. NPT or ISO 7/1-Rc 1.5 threads
• Male pipe nipple, 32 x 50 mm (1.5 x 2 in.) with 1.5 in. NPT or ISO 7/1-R 1.5 threads
• Hot-Tap installation tool (purchased separately)
5.3 Standard Fitting Installation
A. Depressurize and drain pipe.
B. Wearing safety face protection, drill a 32 mm (1.25 in.) diameter hole in the pipe.

C. Install the pipe fi tting of the outside of the pipe according to the manufacturer's
instructions. Failure to follow these instructions may result in serious bodily injury
and/or product failure.
pipe
D. Remove sensor fi tting from sensor assembly.
E. Thread sensor fi tting into pipe fi tting. (Fig. 1)
5.4 Hot-Tap Fitting Installation
A. Install the pipe fi tting on the outside diameter of the pipe according to the manufacturer's instructions. Failure to follow these
instructions may result in serious bodily injury and/or product failure.
B. Install the pipe nipple and isolation valve (ball or gate valve) onto the external pipe fi tting using pipe sealant on the
threads. (Fig. 2)
C. Wearing safety face protection, install an appropriate hole cutting tool per manufacturer's instructions (e.g., Mueller
drilling machine) with a 32 mm (1.25 in.) drill onto the top of the isolation valve, ensuring a tight fi t. Use the
recommended drill bit size or damage to the isolation valve may occur.
D. Open the isolation valve and insert the drill through the valve and cut the sensor clearance hole. After the hole is cut, withdraw the
drill from the isolation valve and close the valve. Remove the drilling machine per manufacturer's instructions. (Fig. 3)

5.5 Calculating the H Dimension
Before installing the sensor some critical dimensions must be established (for Hot-Tap installations,
we assume the pipe dimensions are known). The rotor shaft must be located 10% inside the pipe
I.D. to ensure accurate calibration capability. To accomplish this, the "H" dimension is measured
from the outside surface of the pipe to the bottom of the sensor fl ange.
Nominal "H" dimensions for standard pipes are listed here. For non-standard pipe dimensions,
calculate the "H" dimension using the formula listed below. Your pipe's wall thickness and inside
diameter (I.D.) is required for the "H" dimension calculation.
The 6 inch ruler (included) may be used to measure your pipe I.D. and wall thickness up to 5 inches
(standard sensors only).

5.6 Standard Sensor Installation
A. Thread one hex nut onto each of the three threaded rods
included in package. Install threaded rod with a lock washer
onto the sensor fi tting. Secure rods in place by tightening each
hex nut against the sensor fi tting. (Fig. 4)
B. Thread one jam nut and lower hex nut onto each threaded
rod so that the top surface of each nut is at the proper "H"
dimension for your pipe. Secure each hex nut with a jam nut.
(Fig. 5)
C. Insert the fl ow sensor into the sensor fi tting, making sure the
alignment hole on the sensor fl ange is pointing downstream.
D. Place the alignment rod in the alignment hole on the sensor
fl ange. Align the fl ange so rod is parallel to the process pipe.
(Fig. 6)
E. Thread upper hex nuts with lock washers until they contact the
sensor fl ange and tighten. Check for proper "H" dimension
and readjust if necessary. (Fig. 7)
D. Place the alignment rod in the alignment hole on the sensor
fl ange. Align the fl ange so rod is parallel to the process pipe.
