Fluid Meters

Northwest Pump & Equipment Co. offers the finest fluid meters for a wide range of applications.

  • LC Meters
    • Liquid Controls M, MA & MS series rotary motion positive displacement (PD) meters offer the ultimate in measurement accuracy for custody transfer of petroleum, LPG and industrial liquids. LC meters incorporate a unique design, presenting minimal intrusion in a flowing stream of liquid, plus minimal pressure drop through the meter.

      The LC meter consists of a housing in which three synchronized rotors turn with no metal-to-metal contact. Hydraulic sealing is accomplished by a stationary boundary layer of liquid, not by the wiping action of mechanical parts. Low pressure drop—will operate on gravity flow or pump pressure. Sustained accuracy—no wear from metal-to-metal contact inside the measuring chamber means minimal deterioration in accuracy over time, fewer recalibrations, and longer service life. Meters conform to NIST and International Weights and Measures accuracy requirements.

      Wide temperature range—products can be metered accurately from -40° F (-40° C) to 160° F     (71°C). Wide viscosity range—LC meters can accurately meter products from less than 30 SSU (less than 1 centipoise) to 1,500,000 SSU (325,000 centipoise). Maximum adaptability—right angle design with choice of stock or custom elbows/ fittings provides unequaled mounting flexibility to meet your installation requirements. Rated to 350psi / 21 BAR.

  • Tuthill Fill-Rite Meters
    • Tuthill Fill-Rite offers a full range of positive displacement TS Oval Gear Meters with weights and measures custody transfer accuracy for the measurement of a wide range of fuels, heavy oils, glycols, lube oils, and petro-chemicals. These meters are able to handle the pressure and maintain their accuracy due to the use of only two oval gears eliminating metal-metal contact, fewer seals, low differential pressure, and less slippage due to the patented wave form gear design.

      The TS Series is well suited for use in fuels process / transfer, high speed batching and loading, tank truck meters, LPG systems, stationary dispensing, industrial and petro-chemical refining / processing. Combined with a mechanical register, printer, or solenoid batching, it is possible to build an application specific system that delivers performance, accuracy, and easy maintenance making the TS Series the intelligent choice.

      The Aluminum TS Series offers a full range of metering options ranging from 1, 1-1/2, 2, and 3 sizes with 40-200 GPM at a 150 PSI. These highly precise meters are available in a wide range of configurations to accommodate different temperatures, viscosities, chemical compatibilities, mechanical register calibrations, strainers, filters, air eliminators, air check, backpressure, and preset valves, flanges, and seals.

      Applications
