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.

EFM System Components - cont’d

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.

Figure 8. 4CH Node, 4CH Node Harness and single-sensor cable

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)

has six connectors: four 6-pin female Deutsch connectors (for quad-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).

Sensor and Encoder – Hall effect sensor detects rotation of the encoder magnet on the wheel,

producing pulses at a rate representative of flow.

8-pin node harness terminator – Terminates the series (chain) of product

node harnesses that originate at the ECU. The terminator will always be

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.

App Setup and Operating Screens & Pages

The app provides three main screens for setting up and operating the system:

• Main Overview - up to four pages of information for operating the system

• ECU Settings – for configuring units, values and system options

• EFM Sensor Setup - up to four pages for configuring individual sensors

[Advanced]

• Advanced Settings & Calibration - Advanced Menu and Manual Calibration

The Main Overview screen includes icons at the top, right that provide access to the other screens and

additional menu items.
