Inquiry (采购产品): Flow rate senosr I need a flow sensor that is capable of measuring flows between 50 and 900 mL / min (100-600mL/min minimum) with an adjustable on/off switch that can operate a warning device when flows are outside of the required window. Can you supply a device like this? Please send information with availability and quotation. Thank-you. **** Hidden Message ***** Brent Penner MB R0G 1W0 CAN Company: Dura-Con Industries E-mail: duracon@gninc.ca **** Hidden Message ***** duracon@gninc.ca
