Liquid Fertilizer Monitor Pricing:

This is kind of a do-it-youself project. You will have somewhere around $1000 invested for a 16 row system if you can place all the flow meters within 16" of each other by using the small control box and JST extension wires. For systems with flow meters split (like in folding frame planters with sight tubes on each wing), you will need the large control box and a custom built heavy duty harness. Call for what I've experienced over past 3 years with my system and a couple others. Thick fertilizer mixes with sugar and biologicals may not work well. I run starter fertilizer and biologicals with my infurrow system and straight 32% in my 2X2X2 system.

You will need an Android tablet, a tablet holder, a charging cable such as a USB adapter from a cigarette type port, the app, a wiring harness or extension wires, a control box, flow meters (1 per row), wiring for the control box (+12V and ground), some method of holding the flow meters, a manifold to supply fertilizer to each row (one can mount the flowmeters off the back of existing sight tubes).

For up to 12 gal/acre/row rate, the 1/4" flow sensors are sufficient (1/4" tubing). For higher rates you may need to purchase 3/8" tubing and flowmeters.

Here are approximate prices to build a system:

If you have sight tubes for all rows close together or a single manifold:
Samsung Tab A7 Lite type tablet - $135 to $150
1-16 row control box with JST connectors: $350
App that runs on the Android - $350
Mount flow sensors behind sight tubes or manifold
Flow meters from Amazon - Digiten 1/4 Quick Connect 0.3-10L/min Water Hall Effect Flow Sensor Meter - $10 each
or DIGITEN 3/8 Inch Quick Connect Water Flow Sensor Switch Flowmeter Counter 0.3-10L/min - $8 each
Wiring for JST connector control box, you will need 1 or more extension cables per row:
      I have a limited supply of 20cm extension cables. Check with me.

If you need to mount your flow meters further apart:
Samsung Tab A7 Lite type tablet - $135 to $150
1-16 row control box with 37 pin round AMP connector: $450
Wiring harness for the control box: $40 / row
App that runs on the Android - $350
Flow meters from Amazon - Digiten 1/4 Quick Connect 0.3-10L/min Water Hall Effect Flow Sensor Meter - $10 each
or DIGITEN 3/8 Inch Quick Connect Water Flow Sensor Switch Flowmeter Counter 0.3-10L/min - $8 each

For 32 row systems, add $400.
