S3000 Solvent Meter G3000 and G3000HR (Model 289813 with 90° Sensor Connector Shown) Recognized Component 9902471 Conforms to UL2279 Certified to CAN/CSA E79-0 CAN/CSA E79-11 TI11579a TI14674a II 1 G * 0359 EExia II A T3 ITS03ATEX21212X G250 and G250HR Intrinsically Safe for Hazardous Locations (Class I; Division 1; Group D) when used with an approved barrier only. * CE mark approvals only apply to meters used as part of Graco ProMix, ProMix 2KS, and PrecisionMix II Systems. TI13038a Models Contents Models . [. . . ] The G3000HR and G250HR meters flow volume range is 0. 01-0. 5 gal. /min. Shut off all electrical power to the fluid system. Follow the Pressure Relief Procedure for your fluid system dispensing device. The S3000 solvent meter flow volume range is 0. 01-0. 5 gpm (38-1900 cc/min). NOTICE The flow meter gears and bearings can be damaged if they rotate at too high a speed. To avoid high speed rotation, open the fluid valve gradually. Do not over-speed the meter with air or solvent. To prolong meter life, do not exceed the meter's maximum flow rate. Flow Meter Function This is a positive displacement, gear flow meter. The gear flow meter is highly accurate, even with low flow rates. The fluid flowing through the meter rotates the gears. The gear tooth is picked up by a sensor device, which produces an impulse for every gear tooth passing by. Checking the Meter Accuracy 1. To check the accuracy of the meter, turn your gun fan and atomizing air off, then trigger the fluid into a graduated cylinder; dispense at least 500 cc of fluid. Measure the volume of fluid in the beaker in cubic-centimeters (cc) and read the volume on the flow meter monitor. G3000 and G250: If the flow meter scale factor is not between 0. 112-0. 140 cc/pulse, follow the cleaning procedure on page 10, then recalibrate the flow meter. G3000HR and G250HR: If the flow meter scale factor is not between 0. 05-0. 07 cc/pulse, follow the cleaning procedure on page 10, then recalibrate the flow meter. Air purge is not recommended for any gear-type flow meter. Air purges do not provide the lubrication the meter gears require. Residue Build-up on the Meter Gears Residue build-up may cause the meter gears to bind or stop rotating, which decreases the meter accuracy and makes meter recalibration necessary. As more build-up occurs, recalibration is required more often. The frequency that your meter requires cleaning depends on the type of fluid being used. Excessive residue build-up usually means that you are using improper cleaning solvents and/or cleaning sequences or processes. · Check the meter routinely to develop the correct cleaning schedule. Use the proper cleaning solvent for the fluid being metered. · 308778M 9 Maintenance Cleaning or Servicing the Meter Chamber NOTICE Clean and service the meter at a clean workbench.
