  • Confirm that U-clip retainer is installed and never remove the U-clip retainer when pipe is under pressure–may result in serious injury.
  • Saddle bolts must be tightened evenly. Do not over tighten.
  • Install security seal during installation if regulations require.
  • Improper sealing of cables or cable glands will void warranty.
  • Ensure proper grounding when required.
  • Programming pipe ID, pipe insertion hole size and straight pipe configuration is required for the meter to read.


Choose a position that will ensure a full pipe.Choose a position that will minimize flow distortion.Upstream straight pipe is selected during initial setup. Upstream options are 5X or 10X the diameter and are based on the amount of straight pipe available in either new or propeller meter replacement installation. Downstream straight pipe requirement is 2X the diameter. See programming setup for details.Side (3 o’clock) and top (12 o’clock) installations are acceptable.

BEFORE INSTALLING measure & record inside diameter (ID) of pipe.
  1. Clean the mounting surface, remove any roughness from the area and cut a 1.75″ hole into pipe. Place gasket centered over pipe opening.
  2. Place saddle top over gasket.
  3. Make sure saddle top covers entire gasket.
  4. Place the saddle clamps under the pipe and align with the clamp guides on the saddle top.
  5. Place saddle plates over saddle clamp threads. Attach nuts and tighten as shown below. Torque to 75 ft-lb in cross pattern.
  6. Insert the EX90 sensor into the saddle fitting and secure with mounting clip or attach security clip and seals if required.


Unscrew the display lid and remove it from the meter. Unsnap the display assembly and remove it from the meter exposing the internal wiring connector. Install the wires through the cable glands into the 2 pin screw connector.(C1 = power/output cable)

With Pulse Output Only

Pulse with External DC Power Source9 – 36 VDC at 250mA max, 30mA average
