Liquid Flow

[William Strijks]

How can i create a vi that is reading out a turbine flow sensor and put it in readable or visual data. This data i have to visualize into a report.

I,m using 2 type of Flowsensors:

sensor 1: 1 - 15 l/p min, 2200 pulses per liter, freq 37 - 550 HZ

sensor 2: 2 - 30 l/p min, 1000 pulses per liter, freq 33 - 500 HZ
(See also the datasheet of the Flowsensors)

Hardware: Fieldpoint with FP-CTR-502 and other modules
There is a solution with the ctr 502 but i cann´t use it, because i use the other inputs for something else.

Development software: Labview 6.1

tia, William

once I (ab)used a free input from a fp-quad encoder for such a fluid sensor. wire your output to CHannel A and delayed by a RC (4.7k an 10nF if I remember right) to Channel B. gives you a 32bit counter and flow rate.
just divide the counterchannel by 4*pulses/l to get liter
