Warnings Warnings The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When these symbols appear in the body of this manual, refer back to these Warnings. Product-specific hazard symbols and warnings not covered in this section may appear throughout the body of this manual where applicable.
Warnings WARNING EQUIPMENT MISUSE HAZARD Misuse can cause death or serious injury. • Do not operate the unit when fatigued or under the influence of drugs or alcohol. • Do not exceed the maximum working pressure or temperature rating of the lowest rated system component. See Technical Data in all equipment manuals. • Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all equipment manuals. Read fluid and solvent manufacturer’s warnings.
Installation Installation Installing the Flow Meter • All electrical equipment must only be installed by a qualified electrician. • Understand and follow your local code and safety regulations for hazardous location wiring of intrinsically safe circuits. NOTE: You must assemble the meter sensor to the meter body before connecting the cable to the sensor for the meter to function properly. • Flow volume can only be measured at the location where the flow meter is installed.
Installation Grounding 1. Ground the flow meter by connecting a grounded cable to the sensor. Have a qualified electrician check the electrical grounding continuity between the flow meter sensor and a true earth ground; remove the cable connector from the sensor and measure the resistance from the cable connector Pin B to true earth ground. Refer to FIG. 2. If the resistance is greater than 25 ohms, check the cable ground connection. Refer to FIG. 2. Reconnect the ground sheath or replace the cable.
Operation Operation Pressure Relief Procedure Flow Volume Range The G3000 and G250 meters flow volume range is 0.02-1.0 gal./min. (75-3800 cc/min.). The G3000HR and G250HR meters flow volume range is 0.01-0.5 gal./min. (38-1900 cc/min.). 1. Shut off the fluid supply to the meter. 2. Shut off all electrical power to the fluid system. 3. Follow the Pressure Relief Procedure for your fluid system dispensing device. Flow Meter Function This is a positive displacement, gear flow meter.
Troubleshooting Troubleshooting Before servicing this equipment always make sure to relieve the pressure. NOTICE The sensor is not a serviceable part. Replace it if it is malfunctioning. Problem Cause No flow volume displayed at monitor- Flow volume is too low to measure. ing unit. Fluid is not flowing. Fluid is not flowing. 8 Solution Increase flow volume. Repair. Damaged cable. Replace cable. Improper input voltage to sensor. Make sure input voltage is 10-30 Vdc. Damaged sensor.
Maintenance Maintenance Flushing If the meter is not installed in an instrinsically safe location, make sure the power is off or the electronic sensor is disconnected before wiping the outside of the meter clean with a cloth dampened in a compatible solvent or flushing the meter. NOTICE Do not immerse the meter in solvent with the electronic sensor installed. Solvent could damage the electrical components. Air purge is not recommended for any gear-type flow meter.
Maintenance Cleaning or Servicing the Meter Chamber NOTICE Clean and service the meter at a clean workbench. Use only lint-free cloth on parts. NOTICE To avoid damaging the shafts, keep the housings parallel to each other when separating them; do not rock the housings from side to side. Do not use chisels or screwdrivers to split and pry apart the housings. 7. Remove and inspect the gears and shafts. Clean the meter parts with solvent. 8.
Maintenance Cleaning or Servicing the Solvent Meter NOTICE Clean and service the meter at a clean workbench. Use only lint-free cloth on parts. NOTE: See FIG. 3. Two shim configurations are used. Some meters use one 0.1 mm shim (3c) above each gear (3d) and one below. Other meters stack three shims (.01, .02, and .05 mm, for a total shim height of .08 mm) above and below each gear. When replacing shims, always maintain the configuration used on your meter. One Shim Three Shims 0.1 mm .
