Introduction
The Wilger Electronic Flow Monitoring System (EFMS) is a compact flowmeter that can be used row-
by-row on liquid fertilizer or chemical application equipment. The flow meter is paired with a tablet,
or manufacturer’s monitor to provide accurate monitoring for both blockage and flow rate irregularity.
Similar to visual ball flow indicators, the Wilger Electronic Flow Monitoring System shows variations
in flow caused by blocked lines, incorrect orifices, or blown product hoses. However, the Wilger EFM
System provides the added benefit of indicating the actual flow (not just relative flow) for each row.
This information is conveniently displayed on a screen in your cab.
The EFM system utilizes a paddle-wheel flowmeter, with patented stabilizing flow jets, that maintains
accuracy across the flow range of 0.04 US GPM to 1.5 US GPM (0.15L/min to 5.6L/min), without
significant pressure drops. The EFM system accurately monitors flow on each outlet or product run,
which ensures the operator has complete and comprehensive flow information. The flowmeter can
provide a 40:1 flow range, pairing stabilizing flow jets appropriate for the users’ operational flow
range.
The Electronic Flow Monitoring app (Android OS) receives sensor information from the flowmeters
via an Electronic Control Unit (ECU). The ECU establishes a local WiFi connection with the tablet, so
there are no communication harnesses needed between the implement and the cab.

EFM System Components
Plumbing Components
The Electronic Flow Monitoring system uses O-ring Seal (ORS) plumbing, which is ultimately adapt-
able to any application equipment. However, the system typically requires:
• Plumbing manifolds, which split the flow to each flow run
• EFM flowmeters, each of which is equipped with:
• A flow jet, selected for the anticipated flow range
• An orifice, which determines the application flow rate
• Check valves (recommended) that allow flow to be manually shut off
• [OPTIONAL] Ball Flow Indicators, which can be installed to add visual indication of flow in
addition to the digital display.

Electronics and Cabling Components
The EFM system operates from 12 VDC power (10.8-13.8v). Sensors, nodes and the ECU
are interconnected using multiconductor cables with weather-tight Deutsch connectors.

Extension Cable (Also functions for
Node to Node Connections)
Electronic control unit (ECU) – Creates a
local WiFi network signal that allows the
EFM system to communicate with an
app running on an Android tablet in the
tractor cab. The Android app is provided
free as a download.
[Optional] Extension cables – Two extension cables are
available
ECU/Node to Node (8-pin)
Connects the ECU to the first product node in a chain
of multiple product nodes if a span greater than ~18” is
required.
Available in 12’ or 24’ length.
Node Harness to Quad-Sensor Cable (6-pin)
Connects a Node Harness Divider Cable (A/B/C/D) to a
quad-sensor cable, giving extra length if required.
Available in 6’ or 12’ length.

4-Channel (4CH) Node, 4CH Node Harness, and Single Sensor cable – The 4CH node brings
together signals from up to four flow sensors and sends the signal to the ECU. A
4CH harness connects the node to four single-sensor cables. Each 4CH node has six
connectors: four 3-pin female Deutsch connectors (for sensor cables), one 8-pin female
Deutsch connector (for connecting to the next node in the chain, or to a terminator), and
one 8-pin male Deutsch connector (for connecting to the previous node in the chain, or
the ECU)

8-pin female Deutsch connector (for connecting to the next node in the chain, or to a
terminator), and one 8-pin male Deutsch connector (for connecting to the previous node
in the chain, or the ECU).

plugged into the last product node(s) of the chain.
(Advanced: If an ECU to Node Y-adapter is used at the ECU, two
terminators are required – one on each end of the chain.)

ECU Splitter Cable - The ECU to Node Splitter cable
is used only when plumbing manifolds and EFM
components cannot be centrally located on the
application equipment.
In situations that dictate the EFM components and
plumbing manifolds must be located alongside the
application equipment’s length, the splitter can be
used to minimize the amount of extra wiring and/or
extension harnessing required.
For proper use and labeling of a ECU splitter,
reference Appendix 1.

Tablet and EFM App
NOTE: EFM App can
be available from
www.wilger.net/efm.apk
It may also be available
from the GooglePlay
App store.
Android App requires
Android 8.0 or greater
The Electronic Flow Monitoring (EFM) System includes an Android
app that runs on an Android tablet computer located in the the
tractor cab.
Figure 14. Electronic Flow Monitoring System App on Android Tablet
The EFM app (downloadable from www.wilger.net, GooglePlay Appstore) is relatively simple to
operate and interpret. It provides a highly customizable visual indication of flow rates for each
sensor. Up to three different products can be shown at a time. Up to 196 sensors (shared across
the three products) can be monitored.
Flow alarm thresholds are easily changed for any of the three products. Green balls indicate a
sensor is within the threshold; yellow indicates the flow is approaching, or past the threshold; red
indicates a serious flow alarm condition.
