Inquiry (采购产品): Refrigerant Flowmeter I am searching for a flowmeter to measure the quantity of liquid refrigerant flow through 2-3 sizes of copper tubing. We will monitor the device with a control that supplies 0-5 volts dc. We would also need help determining the formula for determining the rate of flow. **** Hidden Message ***** Dwight Ballard 275 Drexel Road SE bessemer, AL 35022 USA Company: Southern Store Fixtures Title: Lab Technician E-mail: testlab@southernstorefixtures.com **** Hidden Message ***** testlab@southernstorefixtures.com
