INTRODUCTION
Overview
The INSIGHT digital flowmeter has a 4-digit LED flow display with daylight
bright digits 0.56 inch high. The flowmeter is able to communicate with other display
modules over the FRC datalink. This technology allows for remote displays, the display
of flow for multiple discharges (summing), and the totalization of flow for multiple
discharges (accumulation).
During normal operation flow rate information is provided from a paddlewheel
flow sensor or the datalink interface. This information is processed and shown on the
digital display as flow rate.
There are two operator selectable modes; display module identification and
program access. The digital display is used to show stored data or operator inputs
when a selectable mode is accessed. In the display module identification mode the
digital display will show the module serial number, manufactured date, software
revision, module function, and ID number. In the program access mode the digital
display will show operator inputs, program options, and error codes. The operator
selected modes are accessed and inputs are made by using two buttons on the front of
the display module.
All controls and indicators are located on the front of the display module.

GENERAL DESCRIPTION
Components
The INSIGHT flowmeter consists of the following components:
Display Module
Paddlewheel Flow Sensor and Sensor Housing Asembly
Cables
Display Module
The display module is waterproof and has dimensions of 3.25 inches high by 3.26
inches wide by 2.4 inches deep. It is available with optional NFPA color coded bezels.
(The bezels are an intricate part of the display module and must be factory installed.)
All controls and indicators are located on the front of the display module. (Refer to
Controls and Indicators.)
Paddlewheel Flow Sensor
The flow sensor provides an input signal to the display module that is proportional
to the discharge flow rate. It is mounted in the discharge piping. Placement of the
sensor in the piping is critical to obtaining accurate flow rate information, refer to the
installation procedures for detailed information on mounting locations. The electrical
connector is waterproof and molded into the flow sensor housing.
Cables
Interconnecting cables are provided. Refer to Wiring section.

Controls and Indicators
All controls and indicators are located on the front of the display module. It contains
a digital display, two buttons, and an LED display. (Refer to Figure 1.)
Digital Display
During normal operation this 4-digit LED display will indicate flow rate. When
the display module identification or program access modes are selected the digital
display shows module specific information, program codes, settings, and error codes.
See the Programming section for more information.
Mode Button
The display module identification mode is accessed by using the MODE button.
The MODE button is used along with the TOTAL button to enter and input data in the
program access mode.
See Programming section for more information.
Total Button
The TOTAL button allows the operator to display the total flow for a discharge.
When the button is pressed the number shown in the digital display times 100 will be
the total flow. It is also used along with the MODE button to input data when in the
program access mode.
See Programming section for more information.
Totalx100 LED
This red LED is on to indicate that the display will show total accumulated flow
and the number shown in the display is times 100 scale.

INSTALLATION
The DF4000 display module and flow sensor are compatible for use with any size
piping.
Note: Plumbing systems are always unique and may cause small deviations
in the factory calibration. It is recommended that the calibration procedure
be performed after installation.
Install Display Module
The display modules are interchangeable. It is recommended that the calibration
be checked if modules are swapped.
Note: It is recommended to have the flowmeter mounted close to the
associated discharge valve.
1. Measure and mark mounting location for display module panel cutout and
mounting screw holes. Make sure there is clearance behind the panel for the
display and cables before cutting holes. Refer to Figure 2 for layout and
dimensions.
2. Cut out a 2.75-inch diameter hole and drill two holes (clearance or tapped) for
10-32 mounting screws.
3. Place display module in position and secure with two screws.
4. Connect the display module cables and wires. (Refer to Wiring section.)

Install Flow Sensor
There are several ways to install FRC paddlewheel type flow sensors. Mounting
options include saddle clamps, weldments, pipe tees, and special adapters. Each mount
will meet particular plumbing requirements.
Flow sensors are interchangeable. It is recommended that the calibration be
checked if flow sensors are swapped.
The maximum pressure for a flow sensor installation is 600 PSI.
Flow Sensor Location
The location of the flow sensor in the plumbing system is critical. The flow of
water at and around the sensor must be laminar, or smooth, to ensure accurate flow
rate measurement. There must be enough straight pipe run before the flow sensor
location to allow the water stream to stabilize into a uniform flow. Guidelines for
selecting flow sensor locations are outlined in Figure 3.
When the sensor is mounted after an area in the plumbing that tends to increase
water stream turbulence (a valve, increase in pipe diameter, etc.), it is critical that
steps are taken to stabilize the flow.
•When a pipe is reduced in diameter the water stream tends to be squeezed
into a more uniform flow. This can be used to help stabilize flow when
there is not a sufficient pipe run up stream.
•FRC offers an optional flow conditioner that replaces the standard sensor
housing. It protrudes into the water stream at the sensor location and is
specially shaped to reduce local turbulence.
Linearizer Feature
FRC features a Linearizer function in the calibration programming. This function
should be used when the flow sensor is installed in a plumbing location where flow is
not linear. It corrects for nonlinear flow by allowing the display to be calibrated at
multiple flow rates (up to 10) to provide a more accurate flow rate display. (Refer to
Calibration section.)
