OnSite FMS adds digital accuracy to row-by-row flow monitoring of in-furrow and starter fertilizer on your planter.

For Wet Boom Planters

Clean & easy Installs for Wet Boom Planters and Strip-Till Systems.

OnSite FMS+ without the FlowBoards.

Wet boom planters use a hard pipe (or boom) to move the liquid down the planter, breaking out liquid along the way for each row unit. OnSite FMS+ for wet booms work exactly the same as the FlowBoard systems, but they install differently to utilize the wet boom as the manifold instead of having the manifold on a central FlowBoard.

Because of this difference, we move the flow meters out to each individual row unit and measure the flow as it exits the boom for each row instead of grouping them on a central FlowBoard. This requires much less plumbing, but a much longer wire harness to connect each of the flow meters together along the entire length of the planter.

Essentially, the biggest difference between a wet boom system and a FlowBoard system is that you run a wire harness to each row instead of individual hoses.

Simple to install. Easy to use.

Harness Installation

Installing the Flow Meter Harness is simple! It usually just follows the wet boom itself, breaking out for a flow meter at each row. Just secure the harness to the wet boom with zip ties, allowing each leg to break out and follow the liquid hose for each row. The harness is set up for the popular NT style planters with four rows in the rear. If you have a traditional six rear row planter, use the supplied extension cables to route the correct rows back across the fold to the rear.

Flow Meter Installation

To install the flow meters, find a spot in the flexible line between the wet boom and the check valve where you want to add your flow meter. Cut your hose and insert your flow meter right in-line where you cut. Your kit will either come with John Guest or barbed fittings on both sides of the flow meter that insert into splice you just cut. Secure the flow meter to the planter with zip ties and plug it into your flow meter Harness.

Large Planters & Custom Systems

If your planter has more than 24 rows, or if it’s a custom application like a strip-till, you will have one OnSite FMS+ Module for each fold (up to 14 rows) with its own dedicated harness. Each OnSite module connects together with a simple Module-To-Module harness in a daisy-chain configuration. Module-To-Module Connection Harnesses are included with your kit and are sized to fit your application. The last module in the chain will get a terminator at the end. The system will automatically detect all your modules, so you can’t hook them up wrong!

A simple system that simply works.

OnSite FMS+ makes wiring simple! Every plug is unique, so the system can only be hooked up one way. Our Smart Sense technology will also find your modules, order them correctly, and even automatically monitor when sections are turned on and off without complex connections to your field computer.

Bluetooth Systems

Bluetooth systems transfer data from the planter to your cab wirelessly via Bluetooth or WiFi.  They are easier to install because there isn’t any data cable running across the hitch. However, they do need power from both the cab & the planter to power the system.

  • The heart of a wet boom system is the Flow Meter Harness. The OnSite FMS module connects in the center of the harness and may hang freely from the harness.
  • Data is transferred from the OnSite FMS+ Module to the cab via the Bluetooth Module. The Bluetooth Module can be mounted anywhere on the planter, but is usually mounted close to the OnSite FMS Module. The smallest plug on the Module Harness runs power and data to the Bluetooth Module. If the Bluetooth Module is located a ways away from the OnSite Module, you may need an extension cable.
  • On Bluetooth systems, there are two Power Harnesses, one for the cab, one for the planter. The cab harness connects to the cradle cable usually plugs into an aux port inside the tractor’s cab. The planter’s power cable connects to the Module Harness and connects to any 12V power source on the planter.
Wired Systems

OnSite FMS Wired Systems connect the cab and planter together with a physical wire harness that separates at the hitch. Wired systems are the most reliable due to being impervious to interference, and are the best choice if you don’t already have power on the planter.

  • If you are using a wired kit, both power and data will come through the harness from the tractor to the planter.
  • The Monitor-to-Hitch Harness connects to both the Monitor Cradle and an Aux Power port in the tractor’s cab (or directly to the battery). It then runs out of the cab and down to the hitch, where it will connect to the Hitch-to-Module harness from the planter.  
  • The Hitch-to-Module Harness connects to the module harness and runs up to the hitch to meet the Monitor-to-Hitch harness from the cab.  
The Big 7″ Touchscreen Display

One of the best parts of OnSite FMS+ is the big easy-to-read display that sits right in your tractor. The old red ball systems were difficult to see at the best of times, let alone when the dust started flying. Our 7″ touchscreen makes it easy to see exactly how your ssytem is flowing, day or night. The 7″ size is a big enough to read easily, but not so big that it dominates your cab. 

The Display Kit includes everything you need, including a 7″ touchscreen display with charging cradle, a genuine RAM Mount and all the necessary wiring.

To install, just screw the adjustable RAM mount into the tractor, attach the cradle, and drop in your display. The power harness attaches to the cradle and can be run to almost any 12 volt 30 amp power source that is convenient. We always recommend connecting directly to the battery, but the vast majority of installed systems just hook into an aux power port in the cab. The system is fairly low voltage, so almost any 12V power supply will work.
