2 Liquid Controls Liquid Controls MA Series Precise, volumetric, positive displacement liquid measuring principle with minimum intrusion to the liquid flow: No metal-to-metal contact within measuring chamber assures sustained accuracy over service life. Carbon insert bearings reduce friction and wear for extended service life. Low Pressure Loss increases maximum flow rate system. No planned obsolescence means you can rebuild rather than replace. Synchronized rotary measurement principle offers the long est service life in the industry. Precision machined parts produce unequaled accuracy and are totally interchangeable. Ratio gear train is located in the base of the counter where the lack of product lubricity doesn t affect gear train wear. Whatever your LP Gas requirement, Liquid Controls has a meter for the job - fleet fueling, bulk truck, terminal, pipeline, and refinery applications. All meters meet the accuracy requirements of the National Institute of Standards Technology (NIST) and numerous in ter na - tion al weights and measures specifications, and comply with the safety standards established by the NFPA MA Series For operation at any non-shock working pressure up to 350 PSI (25 bar) and at ambient temperatures up to 160 F (71 C). Size for size, LC MA Series are lighter and provide greater mounting flexibility. Accessories may be rotated 180 degrees or covers swapped to reverse direction of flow from L to R or R to L. No additional parts or special tools required. MA 5 For Truck & High Speed Motor Fuel Applications Rate of flow 12 to 60 GPM ( L/min.) capacity range.

7 Liquid Controls Parts CAUTION Diaphragm Replacement Before removing any bolts from the cover, the threaded rod (3/8-16 UNC all-thread bolts 6 long), washer (1 1/2 diameter) and 3/8 nut must be in place to keep spring compressed. The threaded rod is inserted through the cover center hole and screwed securely into threaded hole in diaphragm nut. The washer is then placed onto the rod and the nut is screwed down until spring pressure is felt. The cover bolts can now be removed and cover taken off. The Diaphragm assembly can be removed from cover by slowly loosening the nut on the threaded rod until spring returns to its free length and exerts no pressure on the assembly. CAUTION MUST BE TAKEN TO MAKE SURE THE THREADED ROD DOES NOT UNSCREW FROM THE DAIPHRAGM NUT BEFORE SPING PRESSURE IS TAKEN OFF THE ASSEMBLY. The nut and washer are then removed to take apart diaphragm assembly, spring and cover. FOLLOW ABOVE STEPS IN REVERSE TO REASSEMBLE VALVE.

23 Troubleshooting Guide - Neptune To guarantee that your neptune meter performs at its best, always use Genuine Neptune Parts. Register Does Not Run When Meter Is In Operation A. Loosen the two square-head clamp screws at the front base of the register. Remove the register & look into the bot tom at the change gears. Each change gear has a shear strip in the center hub. If broken, re place complete gear with another that has the same number of teeth (part # Teeth No.) B. While the register is off the meter, check the star drive gear on the meter to make sure it is not slipping on the gear train shaft. If loose, tighten the alien set screw. Also, check the gear train by rotating the star gear with your fingers. You should be un able to turn the star gear a full revolution unless the gear train is bro ken and must be replaced. Meter Flow Rate Decreasing Or Com plete ly Stopped The Dif fer en tial Valve on the discharge side of the meter is designed to require AT LEAST 18 POUNDS MORE PRES - SURE on the inlet side of the meter than the discharge side. This Dif fer en tial Pressure must be present for the meter to operate properly. Check by installing pressure gauges on both sides of the meter and comparing the readings. Insufficient differential pres sure can be caused in the following ways: A. 1) A worn pump, indicated by fluctuating needle on pressure gauge. 2) Wrong size pump. 3) Pump bypass not set properly. 4) Restrictions in suction or supply lines. CAUTION: Before opening any part of the meter, close valve between supply tank and meter. Disconnect coupling in vent line in vapor release cover. Perform the following outdoors, away from building or sources of ignition: Open valve slowly at end of delivery hose or other outlet piping. After pressure is dissipated, unscrew vent valve (hex. nut) slowly (maximum 3 turns) on top of vapor release to depressurize product in meter. B. A defective float or main valve in the vapor release, or ruptured diaphragm (U-cups on 3/4") in the dif fer en tial valve. To check for either of these pos si bil i ties, en gage pump as if a delivery is to be made and shut off vapor line to storage by disconnecting backcheck cou pling on top of the vapor release or by manual shutoff valve (if one is in stalled in the line). Then disconnect the tubing that connects the top of the differential valve to the top of the vapor re lease. After the trapped LPG in this line has been expelled, there should be no evidence of LPG. If LPG continues to es cape from the differential side of this line, the diaphragm, U-cups on 3 4", in the differential is ruptured and needs re place ment. If LPG continues to escape from the vapor release side, the rubber seat of the main valve is worn or has trash on it and needs replacing. Or, the float ball could be collapsed from shock pressure or is fill ing up with liquid, & it needs to be re - placed. C. Clogged strainer in the vapor release. This can cause excessive va por iza tion of the LPG which would prevent the vapor release from closing. Cleaning or re place ment of the strainer will correct this problem; D. Improper vapor return line routing. The vapor line should be connected only to the vapor space of the supply tank. Connection with other vapor lines should be done as close to supply tank as possible. Never connect the va por return line to the pump bypass as this can cause erratic meter per - for mance. Measuring Chamber Repair If none of these checks correct flow rate decrease or stoppage, check the measuring chamber in the meter for foreign matter that caused sticking or jamming of the piston. Clean out all foreign matter and smooth down any score marks on the piston and chamber housing with a 3-sided machinist scraper, and then lightly polish both assemblies with very fine emory cloth. Check the center control roller, the diaphragm, and the seal pin (Ref. Meter Parts List) for wear, and replace those parts as needed. Then reassemble chamber and rotate piston to assure there are no sticking points remaining. WHEN PLACING CHAMBER BACK IN THE METER HOUS - ING, BE SURE TO GET THE LOCATING PIN IN THE HOUS ING ALIGNED PROPERLY WITH LOCATING SLOT ON THE BOT TOM OF THE CHAMBER TO PREVENT CHAM BER DAMAGE. Register Creeping If the meter creeps a few tenths when the pump is engaged, it is probably caused by a worn out or metal-seat inlet check valve. This assembly is found where the supply piping enters the vapor release unit. Replace old assembly with a new rubber seat assembly, which gives a positive seal that prevents bleed back of LPG from the meter. NOTE: IT IS NOT RECOMMENDED TO REUSE OLD GAS KETS If the problem exists after replacing the inlet, check valve as sem - bly, check the delivery hose and nozzle for leaks. If the meter creeps continuously with the pump engaged and delivery nozzle closed, the diaphragm (U-cups on 3 4") in the differential valve most likely has a hole in it and needs replacing. This hole would allow LPG to circulate through the meter & back to storage through the connector and vapor return line (see above). 217

24 Vapor Meter Actaris Vapor Meter The Will-Call delivery is a top-of-the-list concern of propane dealers. Installing vapor meters will enable you to set your own delivery time. A vapor meter not only gives you the ability to deliver gas when you want, but extends your bulk storage muscle to the capacity of each tank in your inventory Vapor - INCREASE CASH FLOW customers will enjoy invoicing on a monthly basis of only the gas used. ALLOW FOR MORE EFFECTIVE GAS PURCHASING with the increased used of your tank inventory for storage, you will be able to buy gas when the time is right. ALLOW FOR GREATER CUSTOMER RETENTION leasing both the tank and the meter helps ensure customer loyalty. All of this is accomplished without the customer being aware you ever filled their tank. The METRIS250 temperature compensated vapor meter provides enhancements and unmatched performance not found in traditional meters. The compact size, reduced weight, long-term proof retention, and a rating of a full 250 CFH (natural gas at.60 sp. gr., 202 CFH propane at 1.53 sp. gr.), make this the meter of choice. The seamless single convolution diaphragm, lubrication-free bearing surfaces, and direct diaphragm support found in the module all contribute to the METRIS's long-term proof retention. Further, since the measurement module is completely removable, meters can be remanufactured in record time by simply replacing the module. No more three-week lead times when repair is needed. The METRIS meter has a Lifetime Case Warranty and a 20-year Accuracy Assurance.
