Liquid Control Meters

Liquid Control positive displacement flow meters are very accurate in measuring low to high viscosity fluids. Fluid volume is directly measured as it goes through the flow meter. LC flow meters are excellent for custody transfer of oil, gasoline, and other refined fuels. Refined fuel trucks and bulk oil delivery trucks are an ideal application for a positive displacement flow meter from MH Pumps.

Liquid Control meters consist of:
  • Positive Displacement flow meters
  • Turbine meters
  • LCMAG Electromagnetic flow meters
Positive Displacement Flow Meters

Meters provide exceptionally accurate service when using MH Pumps unique positive displacement metering principle, even under variable operating conditions (changes in temperature, pressure and viscosity). Provides the energy efficient and functional performance desired from an economical volumetric measuring instrument. Available with traditional mechanical seal or glandless magnetic driven pulse output device. A wide range of accessories are available to meet almost every metering need.

Turbine Flow Meters

Turbine Flowmeters measure volume by means of a precision-crafted, hydraulically balanced rotor mounted in the liquid flow stream. Together, the spinning rotor and a pickup coil (located just outside the flowmeter's wall), generate an AC sine wave signal output. The signal output can be received by many electronic devices, such as registers, totalizers, and flow computers, and then used for flow rate indication and totalization.


LCMass oscillates two equally sized tubes and measures the phase shift between two sensors along the tubes, allowing for an accurate mass flow measurement through application of Coriolis effect principles.

LCMass takes advantage of Hooke's law; a concept describing the frequency response of a spring system, to determine the mass in the measuring tubes.A spring with a greater weight at its end will oscillate more slowly than a spring with a smaller weight. The same is true of the LCMass measuring tubes. From this change in oscillation, the mass, and in turn the density, can be determined.

LCMAG Electromagnetic flow meters

LCMag Meters consist of a sensor and an integrally mounted or remote mounted converter. The LCMag Flow Sensor consists of a lined flow tube, two electromagnetic coils (M), and two diametrically opposed electrodes (E1 & E2). Faraday's Law of Electromagnetic Induction is the basis for magnetic flow measurement.

Faraday's Law postulates that when a magnetic field is created at right angles to the flow tube through which a conductive liquid is flowing, the voltage induced in the electrodes (immersed in the fluid) is proportional to the velocity of the liquid. This induced voltage is converted to a scaled digital pulse output and to a 4–20mA (or 0–20mA) analogue output by the converter. The analogue output signal is a linear output directly proportional to rate of flow.

Liquid Control flow meters are known worldwide for exceptional accuracy, reliability, and longevity in a broad range of applications.

From truck applications metering refined petroleum products and LPG, to process applications metering a wide range of industrial liquids, their combination of low pressure drop with minimum seal or slippage area offers better accuracy over a wide range of flow than other commercially-produced positive displacement flow meters.

Liquid Control flow meters are suitable for batch processing, flow rate control, blending and custody transfer of liquids across a broad range of products, viscosities, temperatures and pressures.

Whether your business requires flow measurement for custody transfer or process control, with a Liquid control meter on your delivery vehicle, at your bulk shipping facility, or at your plant, you'll get years of consistently accurate, trouble-free service. Because of the ease of installation, minimal maintenance, and few replacement parts, you'll appreciate the low cost of owning and operating Liquid control positive displacement meters.
