Built for the field

Real-time sprayer tank monitoring for precision spraying — live gallons remaining on a digital display, fill faster and safer, and never guess how much spray solution is in the tank.

Live digital tank gauge showing spray tank volume on a tablet

See Your Tank Level at a Glance

Cloudy sight tubes stain, fade, and are difficult to read — only a guess at best. Fill Sight is a real-time sprayer tank monitor with a live digital gallon readout on your phone or tablet. Watch every gallon while you fill the sprayer tank from the nurse trailer or cab, without climbing a ladder. Know how much spray solution is in the tank so you know if you can make another pass without running short. No additional displays to mount or purchase — use the phone or tablet you already own.

Tank solution density selection screen

Switch Products Without Recalibrating

Water, liquid fertilizer, and crop protection products all weigh differently. Save up to five density presets and tap the one you're running today. Fill Sight adjusts the volume math on the spot so the number on screen matches what's in the tank.

Detailed calibration table allows for dialed-in fine tuning

Dial In Your Tank Once, Trust It All Season

Easily dial in a calibration table that fits your tank size and shape by filling with water and recording volume levels as you spray the tank out. Fine-tune individual points, turn entries on or off, and get volume readings you can trust when the load has to be right.

Tilt sensor calibration

Accurate Readings on Hills and Slopes

Loading on uneven ground — terrace roads, side of the road, or a sloped yard? The integrated tilt sensor keeps your spray tank volume accurate when the rig isn't level. Zero it once on flat ground, then trust live tank level readings when the ground isn't.

Fill Sight sensor installed on a sprayer tank

Installed in About an Hour

Supply 12-volt keyed power, install the sensor at the tank bottom and mount the control box in the cab or on the frame — that's the core of the job. You'll have your Fill Sight up and running the same afternoon that you open the box.

Fits Your Sprayer — Whatever You Run

Self-propelled, pull-type, small tank or large — Fill Sight works with the rig you already have. Custom calibration maps your tank's shape and capacity, so you're not locked into a one-size-fits-all monitor built for someone else's sprayer.

Designed and Built by Farmers

Fill Sight comes from Wellmann Farms LLC — people who spray fields and know why sight tubes fail. Every system is developed and supported in the USA by a team that's been on the wrong end of a bad tank reading.
