Positive Displacement Meter

Liquid Controls M-Series rotary motion positive displacement (PD) meters offer the ultimate in measurement accuracy for custody transfer of petroleum products, aviation fuels, LPG, and a broad range of industrial liquids. LC meters incorporate a unique design, presenting minimal intrusion in a flowing stream of liquid, as well as 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.
• 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 150psi / 10.5 BAR.

Electronic Registration

Liquid Controls electronic registration has become the standard in the fluid measurement industry.  Offering both process control capabilities and absolute accountability in custody transfer processes. The complete solution from Liquid Controls includes a strainer, air eliminator, electronic registration, and volumetric presetting. An electronic register ties all these elements together to ensure the most accurate most reliable system possible.

Mag Flow Meters

Badger electromagnetic flow meters are designed to achieve ± 0.25 percent accuracy. In addition, the non-intrusive, completely open flow tube design virtually eliminates pressure loss. With no moving parts to impede the flow stream, maintenance is kept to a minimum, even in less than ideal fluid conditions. Available in sizes up to 60” in diameter. Battery Powered models for difficult and remoter locations.

Ultrasonic Flow Meter for liquids

Ultrasonic flow meters are inferential meters that uses ultrasonic technology to measure the velocity of an acoustically conductive liquid moving through it. There are two types of ultrasonic flow meter technologies: Doppler shift and transit-time.

Transit-time measures the time differential between signals sent upstream and downstream. The differential is directly proportional to the velocity of the water. Transit-time meters are best used for measuring the flow of clean liquids and, as a result, are the most popular type of ultrasonic meter.  Doppler shift measures the difference in frequency of the sound wave reflected off gas bubbles or particles in the flow stream and is suitable for aerated or dirty liquids.

Coriolis Flow Meters

The RCT1000 Coriolis mass flow meter identifies flow rate by directly measuring fluid mass over a wide range of temperatures with a high degree of accuracy. For fluids consisting of two liquids or a liquid with suspended solids, this system can derive the concentration and mass of each fluid based on the density measurement. The unobstructed, open-flow design makes it suitable for a variety of fluids, such as slurries and other viscous, nonconductive fluids.

Nutating Disc Water Meter

Nutating disc meters are the most common and accurate type of positive displacement meters. The simple and reliable operating principle allows water to flow into the chamber, which causes the disc to nutate. Each disc nutation represents a fixed quantity of water, so the total flow is calculated by the total number of nutations.
