	Hi there We are looking for an air flow sensor. It needs to measure air flow at up to 200 liters per minute at about 3bar of pressure. The output should be 4-20mA and it can either be hose mounted or some screw thread of about half and inch.

	How about a variable area flowmeter with an attached transmitter? http://www.mess-regeltechnik.at/platon/main.htm#VAMPIRE (usual discalimer). __________________ "Did you get my e-mail?" - "The biggest problem in communication is the illusion that it has taken place" - George Bernard Shaw, 1856

	There are many different types of flowmeter that would do the job as you have described it.... But there are further specifications that are needed to narrow down the search first... Such as accuracy required? The flow range or 'turn down' - is it only 200 l/min or 20 to 200 l/min? How is it to be mounted, what supplies are available etc... environmental conditions and so on...
