FT-4600 QUICK START GUIDE
SECTION 1.0: UNPACKING
The FT-4600 is generally shipped in one package unless optional hardware or equipment is ordered. Notify the freight carrier and ONICON if any items are damaged in transit.
1.1 CHECKING THAT YOU HAVE RECEIVED EVERYTHING
The following items have been provided with your FT-4600 Flow Meter:
Please notify ONICON if any of these items are missing. *NOTE: The 2½” version of the meter is provided with flanges
SECTION 2.0: INSTALLATION
2.1 SITE SELECTION
Before you install the meter, the entire piping system should be flushed and
free of debris. Please refer to the diagrams below when selecting the
installation location. Upstream straight unobstructed pipe requirements vary
considerably based on the nature of the upstream obstructions. It is always
recommended that the meter be located with as much straight pipe upstream as
possible.
2.2 MINIMUM STRAIGHT-RUN REQUIREMENTS
Upstream Obstruction| Minimum Upstream Straight Run Required (Pipe
Diameters)
---|---
Meter Size
0.5 – 1.0″| 1.25 – 2.5″
Single Elbow| 0| 0
Expander / Reducer| 0| 0
Coil, Upstream| 3| 3
Isolation Valve, 2 Position| 3| 5
Control Valve| 10| 15
Notes:
1| Straight run is based on use of manufacturer provided couplings
2| Avoid the following obstructions where possible: Modulating valves, pump
discharge, multiple elbows out of plane.
2.3 INSTALLATION DETAILS
- The flow meter MUST be correctly oriented as in the picture below to ensure proper function. Failure of installing the meter as shown below will result in erratic readings due to the accumulation of debris or air pockets in the meter body.
2.3 INSTALLATION DETAILS (cont.)
- The maximum operating pressure for the fl ow meter is 400 psi.
- The operating ambient air temperature range is -13°F to 131°F.
- Do not install the meter in close proximity to strong sources of electromagnetic interference (e.g. electric motors, VFD’s, fluorescent light fixtures, etc.)
A. This is a recommended position for the flow sensor.
B. This is a recommended position for the flow sensor.
C. Avoid installation locations where air can become trapped in the piping
system.
D. This is an acceptable installation location for closed-loop pressurized
systems.
E. Do not install the sensor downstream of modulating valves or partially open
valves. Fully open isolation (e.g. ball valves) are OK.
F. Do not install the fl ow sensor at the inlet of a pump. To prevent
cavitation, the minimum operating pressure at the inlet of the meter must
always exceed the pressure drop across the meter. Refer to Appendix A-3 of the
manual for calculating pressure drops at different flow rates.
G. Avoid installing the meter downstream of multiple bends out of plane with
each other where there are less than 10 diameters of straight unobstructed
pipe between bends.
SECTION 3.0: POWER AND SIGNAL WIRING CONNECTIONS
The FT-4600 is provided with an unterminated 10 foot PVC jacketed cable for
power and signal connections.
Do not attempt to remove this cable. Doing so will damage the weather-tight
seal and may void the product warranty. Use 18-22 shielded cables for power
and signal connections. The analog signal is active. Do not connect external
voltage to the blue & brown wires.

SECTION 4.0: LED LIGHT STATUS AND SIMULATION
The FT-4600 will have a steady LED light on the front cover when it is operating properly. Refer to the QR code and manual if the LED light is blinking. For flow simulation, press and hold the SW2 button. The flow meter will enter on simulation mode. The meter will simulate 20mA and it will pulse accordingly. Press the RST button to exit simulation mode.
