I bought this meter to monitor coolant flow rate in some equipment, nominally about 1 Lpm. It is not positive displacement, but rather operates as a nozzle aimed at a paddle wheel, so very low flow will not register. At mid-range flow, it produces about 15,000 pulses per gallon (roughly 10 to 100 Hz). The nozzle is only about 1.25 mm in diameter, so the pressure drop is rather high. I measured 12 PSI drop at 1 Lpm flow, so this may present a problem in some situations. It is possible to disassemble the unit and drill the orifice larger to reduce the pressure drop if reduced sensitivity is acceptable. The electrical interface I used was +5V (Red), Common (Blk), and Signal (Yel). The output swings properly and without noise for trouble-free interfacing, at about 50% duty cycle. I have not tested it for presure or temperature. For the price, I can't complain about its performance.
