FlowHD: Installation Instructions & User Guide
Introduction
The FlowHD is an ultrasonic flow sensing device that accurately reads flow and precisely delivers the
flow data you need to reduce water waste and increase efficiency.
The FlowHD device is available as a complete unit, or as a retrofit option.
Existing Data Industrial 228PV flow sensors can be upgraded without having to remove the entire flow
sensor. The existing insert is removed and replaced with the FlowHD insert. Instructions are included in
this guide.
This guide will help you through the installation process and provide troubleshooting tips if needed.
Please read carefully before starting.

Do not Install onto Elevated Pipes
It is important that the FlowHD not be installed onto an elevated pipe. If you must install a FlowHD
near an elevated pipe, the FlowHD should be installed BEFORE the elevated section, as illustrated
below.
Installation Best Practices
Choose a Location Downstream and Past the Master Valve
Before installing the FlowHD, it is important to select the proper location on the mainline. The location
must be past the master valve and backflow.

3
Familarize Yourself with the FlowHD Parts and Pieces
Familiarize yourself with the meter before installation. Below is a drawing of a typical meter with
labeled components.
Note: The Tee is bidirectional, the insert is not. The insert operates correctly as long as the insert
arrow is pointed in the direction of flow. The insert can be rotated 180 degrees, so its arrow can
always be pointed in the direction of flow regardless of Tee installation.
Go Downstream
When installing the FlowHD, you will need to provide a straight pipe run of at least 10 times the pipe’s
diameter upstream of the meter, and at least 5 times the pipe’s diameter downstream of the meter. The
arrow embossed on the insert body denotes the flow direction.

Installation Instructions
Install the Device at an Angle
The FlowHD must be installed at an angle. Installing the FlowHD at an angle prevents too much air
from being trapped inside the device. When too much air gets trapped inside, false readings can
occur.
Recommended angle degrees corresponds to size of the pipe that the FlowHD is attached to.
For 1” pipe install the FlowHD at a 45 degree angle.
For pipes that are 1.5”- 4” install the FlowHD at a 20-45 degree angle.

5
Part 1: Preparing the Installation Area
3. Select a location for the FlowHD install. Make sure the location is downstream and past the master
valve and backflow (See Installation Best Practices). When digging the hole, for the valve box, make
sure it is big enough to accommodate a valve box that is large enough for easy installation and
maintenance.
2. Flush water out of the mainline.
CAUTION! Before proceeding, It is important to flush water out of the mainline. Failure to do so may
result in water flooding into the hole being trenched for the install or debris from the mainline covering
up the ultrasonic sensor.
1. Turn off the water to the pipe area where the FlowHD will be installed.

6
2. Apply primer and cement to the pipe ends and t-sockets and quickly assemble the parts while the
cement is fluid. Follow the cement manufacturer’s instructions for drying time and additional
instructions.
Caution: Avoid excessive cement use. The excess can flow downstream and clog valves and sprinklers.
Part 2: Connecting the FlowHD to PVC or Mainline
1. Remove all burrs from the pipe tee sockets edges. Clean edges.

7
3. Install the meter with the arrow on the insert pointing in the flow direction.
Note: If the meter is accidentally installed backwards, simply remove the insert, rotate 180 degrees so
the arrow points in the flow direction, and reinstall the insert.

8
6
The FlowHD must be connected with 3M™ DBR/Y-6 wire splicers. Follow manufacturer’s instructions
when using the 3M™ DBR/Y-6 Wire Splicers.
Best practices include:
 Stripping insulation 3/4” from the connecting end
 Ensuring the connector is inserted all the way into the tube until the connector rests on the bottom
of the tube
 Ensuring there is no water intrusion into the connector
 Tightening connections until secure
NOTE: If having difficulty getting the twist-on connector down into the tube when using small gauge
wires, use a thin, non-conductive object to push the connector to the bottom of the tube. Upon
removal of the object, ensure that no voids or water paths remain in the gel.
Wiring Connections for the FlowHD
1. Connect the wires from the FlowHD Device to the field wires, using the diagram below as a guide.
Part 3: Wiring Connections

9
1. Turn water back on and run water through the FlowHD and surrounding pipe.
2. Check to see that the connections are watertight. Ensure the seals on the piping are working
correctly and that no water is leaking.

Troubleshooting
The LED’s are the primary indicators of meter performance. There are two LED’s on the Flow HD. The
Green LED is used to indicate basic power and functionality of the meter. The Amber LED is used to
indicate that there is a flow of water through the FlowHD meter insert. The LED’s will behave in the
following manner to indicate different modes of operation:
Mode LED Behavior
Power Disconnected or Meter Failure Both green and amber LED lights are off
No Flow Low Power Mode Green LED flashes ON/OFF at a rate of approximately 2
blinks per second
No Flow or Reverse Flow Active Mode Green LED flashes ON/OFF at a rate of approximately 8
blinks per second
Low Flow Active Mode Green LED flashes ON/OFF at a rate of approximately 8
blinks per second and the amber LED flashes ON/OFF at a
rate that is proportional to the rate of water flow through the
meter.
High Flow Active Mode Green LED flashes ON/OFF at a rate of approximately 8
blinks per second and the amber LED will appear to be con-
stantly on, but will be dim.
Best Practices
 The faces of the FlowHD need to be clean and free of oily substances for accurate operation. Do
not touch with fingers, oily rags, etc.
 Do not use wire brushes or abrasives to clean the FlowHD.
 Ensure the flow direction arrow is pointing in the direction of flow for correct LED functionality.
 Ensure the quick release pin is installed in the tee to maintain pressure and alignment of the insert
in the tee.

Retrotting a FlowHD into an Existing Flow Meter
Checking Meter Size
If your flow controller requires a meter K-factor, use the K-factor for your size meter (see
SPECIFICATIONS section). If the meter size is unknown, it is easily determined using one of the
following methods:
Dipstick Method (For 2 in., 3 in. and 4 in. meters only):
The interior depth of the meter body indicates its size. To check, remove the old insert from the
meter body and insert the end of a stiff tape measure down into the insert bore until it touches
the bottom of the meter body bore. Read the depth shown on the tape measure at the top of
the tee housing.
Compare measurement with the “Depth Value” in the Specifications for Pipe chart and order
accordingly.
Line Pipe Size Method: Normally, the line pipe size is the same as the meter size
Before proceeding, you will need to check the existing flow meter size to ensure you have the correct
retrofit FlowHD device.

13
Make sure area is clean before removing the insert to ensure no dirt falls into the insert hole.
1. Pull out the quick release pin from the meter.
2. Remove the old insert. Grasp the insert flange with your hands and pull straight up and out of the
tee, making sure no dirt or other particles fall into the insert bore of the meter.
3. The tee insert bore must be clean before installing the insert and the 2 black O- rings on the insert
should be fully lubricated.

7. Replace the quick release pin.
8. Follow steps outlined in Parts 3 and 4 of this guide for wiring, flow validation and controller configu-
ration.
4. Orient the insert over the insert bore so that the arrow on the insert is pointing in the direction of
flow.
5. Insert straight down into the tee, and push down on the insert flange.
6. Twist slightly to install and to align the retaining pin holes in the insert with the holes in the tee.
