Warnings

Refer to instruction manual for further details.

  • 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.

Positioning

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.

Wiring

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

With No External Output – If not using external output, no wiring is required.

EXTERNAL POWER WARNING!Ribbon cable must be connected BEFORE external power is applied. See Instruction manual for details.

WARNING: Improper sealing of glands or cables will invalidate any warranty. If plugs or cable glands are removed, reinstall using Teflon pipe sealant, or tape, to ensure maximum moisture protection.

Remove plug & o-ring. Insert cable gland/strain relief. Feed cable through cable gland.Clamp cable with strain relief clips. Attach drain wire lug to bracket post.Torque cable gland sealing nut to 22 in-lbs.

Menu System

The HOME Screen displays flow volume, direction of the flow total and flow RATE along with status conditions such as Empty Pipe. Two buttons below the LCD display are used to access menu screens for viewing and changing meter setup parameters.

These two buttons are light sensors which can detect when a finger is covering them and activate upon release. Only three button touch actions are needed to control navigation through the menus, settings changes and back to the home screen.

INITIAL SETUP OF ID, HOLE, AND PIPE IS REQUIRED FOR THE METER TO OPERATE PROPERLY.

  1. SETUPView or change meter configuration settings.
  2. SETUP (Menu Functionality)The highlighted value can be changed using the arrows. The value on the left is the menu name. Cycle through these by pressing . Press to highlight and change the value of the menus.
  3. ID (Required)View or change inner diameter of the pipe. Measurement in inches.
  4. HOLE (Required)View or change installation pipe hole size. Tap then to change setting from N/A (default) to small and large sizes.Note: See instruction manual page 14 for hole size description.
  5. PIPE (Required)View or change pipe configuration based on installation. Tap then  to change setting from N/A (default) to 10/2, 5/2 or STRAIGHT (conditions with 10 diameters or more)

INFO: Meter model, serial number, firmware version

SAMP: Sample rate (Default is set to 5 seconds. Battery life with a 5-second sampling rate is four years. Increase sampling interval to extend battery life. (May vary depending on environmental factors. See instruction manual for more details.)
