Approval of FL-S402B is required.

We need the CONNECTOR/Crimping pin specifications for this sensor test.
We need it for the design of the counterpart that needs to be connected to control this part.
If you send us the FL-S402B approval, we can use it more usefully.

Flowmeters used for liquid fertilizer monitors for farming in-furrow and 2X2X2

I am using the Digiten flowmeters for my starter and 32% fertilizer (12% thicker than water). It's great to watch the graph of gallons per acre...so much better than watching sight tubes. The meters work better than expected. I've had 2 failures over the 2 years running 24 meters on my planter. The meters run continuously for 8 - 16 hour days, 12 days a year in harsh conditions with corrosive chemicals. My lab testing showed accuracy to be very good.

Works correctly as long as you know what you're getting

The results at various rates appear to correlate quite linearly with a r^2 value of 0.9998. Although if you want more precise results than the "38 * Q" figure given by the manufacturer you will have to calibrate the readings yourself.

To address the previous review-- the meter does not report volumetric flow directly. Instead the counts reported represent the speed of flow. Which is exactly why the number changes with flow rate. Volume is then determined by multiplying the cross sectional area with number of pulses and a speed constant while correcting for liquid density, temperature, etc. Certain properties can be disregarded such a temperature, density, etc. and replaced with constants if absolute precision is not required.

Short version-- once you boiling it all down to the basic formula what you need in order to determine volume is number of pulses and time. If flow rate changes over time you will need to slice the readings into smaller intervals and integrate the values.
