Rated 5 out of 5 by Muhammad Azeem Ghouri from Digital Flow Sensor This flow sensor that I bought works well. The display makes it very convenient to control the flow rate. I highly recommend it.

Rated 5 out of 5 by mschmid from Easy and Reliable We have several of these FLR series flow meters in the lab. They are easy to use, and very reliable.

Rated 1 out of 5 by Sarath from VERY POOR! Wrong Reading! Bought this flowmeter and tested it (measuring cylinder and timer)only to realise the reading was way off the mark. Please be careful, look for a calibration certification if you plan to get one.

Rated 4 out of 5 by Pat W from C+ to B- FLR1204 20-100L/min works. Spec sheet states "fast response" I did not find this to be true. Power requirements states 30mA (typical) with 11.5 V to 15.0 V supply, so 0.345 W to 0.45 W. Data logger has .4 W. Will data logger power the senor or not??? Also, the FLR1204 sensor is on a by-pass plumbing, I was not aware of this.

Rated 3 out of 5 by Bhampton from works and functions but limited Purchased unit but had to return the first one due to a defect on the screen. got the second one in and it works great, in an environment without any back pressure. The second any pressure is added to the mix the gauge is rendered useless. unfortunately the testing we are performing requires some pressure while still maintaining flow and we are not able to get the value we are looking for. looking at other gauges that might have a different system to make our test work.
