GPI LM50DB Instruction Manual

INSTRUCTION MANUAL This meter is designed for in line use with Engine Oil & ATF up to a maximum viscosity of SAE 140, Diesel & Water Gly- col mixtures with a maximum water content of less than 50%. Please read and retain this instruction manual to assist you in the operation and maintenance of this quality product. GENERAL INFORMATION This manual assists you in operating and maintaining your new positive displacement flowmeter. The information contained will help you ensure many years of dependable performance and trouble free operation. Please take a few moments to read through this manual before installing and operating your new meter. If you experience problems with this product, refer to the Maintenance and Trouble Shooting sections of this manual. If you require further assistance please contact your local GPI Distributor. IMPORTANT INFORMATION The GPI quality Positive displacement flowmeter has incorporated the oval rotor principal into its design. This has proven to be a highly reliable and highly accurate method of measuring flow, providing exceptional repeatability and high accuracy. GPI recommends, that if you are using your meter as an in- line application you should install a filter before the inlet of the meter. Contact your local GPI distributor for further details. INSTALLATION 2) Do not over tighten connections. 0002 OPERATION LM50DB or LM50DN ELECTRONIC REGISTER DISPLAY BUTTON Each press of the DISP button will allow you to scroll through the meter options Resetable Batch Total Resetable Accumulative Total Non Resetable Accumulative Total Flowrate RESET BUTTON The RESET button allows you to reset the Batch Total or the Resettable Acumulative Total to zero. To reset either the Batch total or Resetable Acumulative total. Press the DISP button to scroll to either the Batch or Resetable total . When the required total is displayed. Press reset to zero the totalizer. FLOWRATE This display option shows the flowrate of the fluid passing through the meter. IM083 0106 POSITIVE DISPLACEMENT FLOWMETERS

the line pressure is released before disassembly. METER REASSEMBLY 1) Replace both rotors (4) so as they are at 90 O to each other. (see fig 2). Check the rotor rotation by turning either of the rotors. If the rotors are not in mesh correctly or do not rotate freely remove one of the rotors and replace it correctly at 900 to the other rotor. Re-check the operation of the rotors. 5) Test the meter by turning the rotors with a finger or by applying low air pressure (No more than a good breath) to the inlet port of the meter. This will confirm the meter is operating correctly. 1 2 5 6 7 4 3 PARTS LIST BATTERY REPLACEMENT 1) Remove the plastic protector shroud from the meter body. (fig 1) 3) Replace the 2 x (AAA) Alkaline batteries. (Refer to the front of the meter for correct battery orientation). Note: Only use Alkaline batteries. If NO flow goes through the meter for 60 seconds the display will go into sleep mode (Blank). The display will automatically wake if the buttons are pressed or flow occurrs. SLEEP MODE Note: The electronic computer module is non-repairable. The meter will need to be replaced if found to be damaged or faulty. 1) Remove the 8 x philips head screws (1) from the meter cover. 2) Remove the meter cover (2) and o’ring (3). 3) Remove both rotors (4). 4) Clean and inspect all parts. Replace any suspect, worn or damaged components. NOTE: Ensure the rotor with the magnets is assembled on the same side as the batteries. The magnets in the rotor must face towards the electronic display . The Rotor with Magnets ( fig 2) (fig 1) magnets Note: Replace the batteries as soon as the battery indicator on the LCD is displayed + - 2) Remove the battery cover. 4) Replace the battery cover and re-fit the plastic shroud. All data will be saved when the batteries are removed. 2) Lightly grease the o’ring (3) and place it on the meter body. 3) Clean the meter cover plate (2) and place it on the body. Take care not to damage the o’ring (3). 4) Install the 8 screws (1) and tighten in a diagonal pattern to 1nm (0.73 ft.lb). Visual check the cap has been pulled down evenly.
