Fluid Meters

Fluid Meters

Fluid meters are designed to monitor fluid flow rates of water and solvents. These meters closely resemble their water-based fluid counterpart, with the exception of different internal wetted components for fluid compatibility.

LC Meters

LC Meters

Liquid Controls M & MA Series of rotary motion positive displacement (PD) meters provide the ultimate measurement accuracy for custody transfer of petroleum, LPG, and industrial liquids. In addition to presenting minimal pressure drop through the LC meter, it incorporates a unique design that minimizes intrusion into a flowing stream of liquid.

Positive displacement meters from Liquid Controls have been designed to provide an accurate, trouble-free service life with minimal maintenance. LC meters have a unique construction that results in low-pressure drop for most liquids, delivering superior performance and reducing the demand on the pump system.

Superior Performace Features:

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.

Wide temperature range: products can be metered accurately from 40° F (-40° C) to160 ° F (71°C).

Wide viscosity range: LC meters can accurately meter products from less than 30 SSC to 1,500,000 SSU.

Maximum adaptability: right angle design with a choice of stock or custom elbows/ fittings provides unequaled mounting flexibility to meet your installation requirements.

Tuthill Fill-Rite Meters

Tuthill Fill-Rite Meters

Tuthhill 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 petrochemicals. 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 waveform gear design.

TS Series has been well suited for use in fuels transfer and processing, high-speed batching and loading, stationary dispensing, and industrial and petrochemical refinements and processing. Combined with a mechanical register, printer, and solenoid batching, it is possible to build a system that provides performance, accuracy, and easy maintenance, making the TS Series a smart option.

Lastly, 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, airchecks, back pressure, and preset valves, flanges, and seals.


  • 150 GPM (570 lpm) Max
  • 150 psi at 100°F = 10 bar at 40°C
  • 2 Bolted Companion Flanges with NPT or BSP port
  • Meter Only is CE and ATEX Certified

Total Control Meters
