Think & Do Question
Think & Do Question
(OP)
Hi all,
I am totally new to Think & Do software and in need of some help.
I have a Weighing stool with four load cells on and a tank. The tank is to be filled with water and weighed but I need to calculate the flow rate of water (different rates) going into the tank and display on my HMI. The data coming in for the weighing cells is serial data and I convert it from a string into floating points which are summed together to give total "gross" weight. So from this floating point, I would like to calculate the flow rate in KG/Min of the water when filling. The load cell capacities are 2000 KG each therefore the total stool capacity is 8000 KG. Hope someone can help thanks in advance

RE: Think & Do Question
Overall weight = always displayed
Start of flow = weight1 in time+0
Sample of flow = weight2 in time+1
Calculate flow = weight2 - weight1 in time(time+0 to time+1 = example 5sec)x12 = kg/min
Then after every 5secs do the calculation, then move weight2 into wieght1, after 5sec do calc again for a running flow kg/min
Probably missed something but above should get you in ballpark.
