Looking for a flow sensor
Looking for a flow sensor
(OP)
Hello,
currently I am working with high pressure hydraulic torque wrench pumps. I am looking for a flow meter with ability to integrate it in hydraulic system which pressure is up to 1000bar. The flow range of oil I need to measure is up to 7l/min. Could you please offer me a list of flow meters for my system? Also the sensor could have analog output either switching contact like PNP or NPN transistor. Thank you for your reply.

I don't know where to get a "flow switch" or what technology it would represent. One thing you can do is put a dP gauge across some flow restriction that can't go all the way shut (a restriction orifice is a good choice). If there is a dP then you have flow. No dP? No flow.

That is significantly different from the original question. Normally a pressure switch or valve is used to sense end of stroke on a cylinder. The pressure will rise to relief valve pressure at end of stroke. There are valves made just for this purpose.

Here is an off the shelf item that goes to 410 bar.

Another option is an ultrasonic flowmeter. Something like this perhaps:
