Safety Warnings When installing, operating, and maintaining McCrometer equipment where hazards may be present, you must protect yourself by wearing Personal Protective Equipment (PPE) and be trained to enter confined spaces. Examples of confined spaces are manholes, pumping stations, pipelines, pits, septic tanks, sewage digesters, vaults, degreasers, storage tanks, boilers, and furnaces. -
Page 4: Unpacking And Verifying Components
Unpacking and Verifying Components 1 .0 UNPACKING AND VERIFYING COMPONENTS The FPI Mag® (Full Profile Insertion) flow meter provides accurate flow measurement for full-pipe clean water applications. The electromagnetic sensor automatically senses and corrects for shifting velocity in the pipe by constantly obtaining an area weighted mean velocity. -
Page 5: Verify Serial Numbers
Unpacking and Verifying Components 1 .2 Verify Serial Numbers The FPI Mag flow meter is comprised of two primary components: the sensor and the converter. The converter and sensor are supplied as a custom calibrated matched system. Verify the system serial numbers on both the converter and sensor match. -

Page 7: Step 1: Names Of Sensor Components
Sensor Probe Installation STEP 1: Names of sensor components This manual refers to the part names of the sensor. It is important to be familiar with the parts and their names as shown below in Figura 5 when following the installation instructions. For a full list of replaceable parts with part numbers, see Section 7.0. -

The upstream and downstream straight-pipe recommendations are conservative, based on research completed in the McCrometer NIST traceable calibration facility. In many cases, the installation distances suggested below can be shortened depending on flow conditions and piping layout. - Page 9 Filter Note: The table above is not inclusive of each possible installation scenario for the McCrometer FPI Mag. For installations not included in the table, the McCrometer Applications Team is available to review cases and make a determination as to the viability of the installation.

Sensor Probe Installation STEP 5: Installing the pipe valve WARNING! Pressurized pipes should only be hot tapped, cut, or drilled by qualified personnel using high quality saddles, valves and stainless steel nipples.

Page 12: Step 6: Ensure Sensor Will Be Installed Perpendicular To The Pipe
Sensor Probe Installation 90° 90° STEP 6: Ensure sensor will be installed perpendicular to the pipe The FPI should be installed perpendicular to the pipe as shown in Figura 12 for a vertical installation. The allowable tolerance for installation is ± 0.5°. A perpendicular installation is determined by the coupling that is mounted on the pipe. Prior to installing the FPI a level ruler should be used to check the coupling and ensure that it sits level. -
Page 13: Step 8: Connecting The Sensor Onto Pipe Valve
Sensor Probe Installation STEP 8: Connecting the sensor onto pipe valve The sensor assembly uses a compression seal, which keeps the sensor watertight when the pipe is under pressure. Care must be taken when installing the sensor to avoid leaks. Follow the steps below to install the sensor onto the pipe valve: Put a generous amount of the pipe sealant or Teflon tape on the compression seal threads. -
Page 14: Step 10: Insert The Sensor Probe Into The Pipe
(Figura 18) NOTE 3: Using the sensor insertion tool McCrometer recommends using a sensor insertion tool (see Figura 19) to rotate the captive nuts. This will ensure the top plate compresses evenly and will help avoid any damage to the sensor. - Page 15 Sensor Probe Installation Follow the steps below to insert the sensor probe into the pipe . If you disassembled and reassembled the compression seal, hand tighten the compression seal bolts and nuts. DO NOT FULLY TIGHTEN THE COMPRESSION SEAL BOLTS AND NUTS. If you did not disassemble the compression seal, proceed to step 2.

Page 16: Step 11: Apply A Compression Load To The Sensor
Sensor Probe Installation STEP 11: Apply a compression load to the sensor A compression load is required to be applied at the top of the sensor forcing the bottom of the sensor to seat firmly against the far wall of the pipe. The amount of load is indicated by the three lines etched into the top plate and the location of the set screw relative to the lines. -
Page 17: Step 12: Install The Retaining Rods
Sensor Probe Installation STEP 12: Install the retaining rods After the sensor has been inserted and the load adjusted, remove the insertion rods and install the shorter retaining rods. This will make the sensor assembly more compact. (Figura 25) NOTE If the short retaining rods are not used, run a 3/8"... -
Page 18: Step 13: Attaching The Ground Wire
Sensor Removal STEP 13: Attaching the ground wire The FPI meter is electrically continuous to a conductive (non PVC) pipe through the retaining rods. Additional grounding may be required to a dedicated earth ground via ring terminal and 10 AWG wire (not provided). -
Page 19: Electronics Installation
Electronics Installation Once both of the long retaining rods are securely in place, completely remove the short retaining rods. Loosen the compression seal bolts until the seal just begins to leak. This will relieve the pressure on the compression seal allowing the sensor to be removed. Draping a towel around the compression seal can reduce any spraying water. NOTE: The compression seal may prevent immediate leakage on sensors installed for a long period of time until the sensor begins to rise. -
