Coriolis Mass Flowmeters
A Coriolis flowmeter contains a tube that is energized by a fixed vibration. When a fluid (gas or liquid) passes through this tube the mass flow momentum will cause a change in the tube vibration, the tube will twist resulting in a phase shift. This phase shift can be measured and a linear output derived proportional to flow.
*Up to 8 inch
*Up to 9000 kg / min
Turbine Volume Flowmeters
A turbine Flow Meter is a volumetric measuring turbine type. The flowing fluid engages the rotor causing it to rotate at an angular velocity proportional to the fluid flow rate.The angular velocity of the rotor results in the generation of an electrical signal (AC sine wave type) in the pickup. The summation of the pulsing electrical signal is related directly to total flow.
*Up to 6 inch *Up to 9000 l / min
Vortex Volume Flowmeters
Vortex flowmeters operate under the vortex shedding principle, where vortices (or eddies) are shed alternately downstream of the object. The frequency of the vortex shedding is directly proportional to the velocity of the liquid flowing through the meter.
*Up to 6 inch *Up to 9000 l / min
Magnetic Volume Flowmeters
Electromagnetic flow meters (or magmeters) are a type of velocity or volumetric flow meter that operates according to Faraday’s law of electromagnetic induction – which states that a voltage will be induced when a conductor moves through a magnetic field.
*Up to 6 inch *Up to 9000 l / min
Ultrasonic Volume Flowmeters (USM)
Ultrasonic flow meters, which are a type of volumetric flow meter, are non-intrusive flow sensors that use acoustic vibrations to measure the flow rate of a liquid.
Positive Displacement Flow Meters
Positive Displacement flow meters are the only flow measuring technology to directly measure the volume of fluid that passes through the flow meter. It achieves this by trapping pockets of fluid between rotating components housed within a high precision chamber.
*Up to 6 inch *Up to 3000 l / min
Pipe Prover / Prover Loop
A pipe prover is an apparatus that authenticates and calibrates the readings obtained from a liquid or gas flow meter. While these devices can either be manual or automated, the most popular and newer prover systems are automatic devices.
Compact Prover / Small Volume Prover (SVP)
Compact provers work by passing a known volume of air through a meter while monitoring the gas meter's register, index, or internal displacement. The prover then displays a proof, a value expressed as a percent which compares the volume of air passed with the volume of air measured to determine the meter's accuracy.

Metering Instrumentation Technology
Validation of pressure, temperature, differential pressure transmitters
- Mogas’s metering validation service offers the following:
- Calibration of pressure and differential pressure transmitters calibrated to ensure a high standard of accuracy and traceability.
- Calibration of temperature transmitters, or where applicable flow computer RTD inputs.
Calibration and maintenance of flow control valve (FCV)
- The purpose of a flow control valve (FCV) is to maintain the desired portion of the flow to each flowmeter individually and allocate a portion of the flow rate to meet scheduling requirements for the month, week, day, or hour.
Meter Proving System
Operating of GRAVIMETRIC METHOD system
- A gravimetric method provides high accuracy, high precision in rapid operation. A static start and static stop process with weighing scale. This is accomplished without affected by temperature and pressure change.
Operating of Master Meter Proving System
- A master meter proving system can either function to calibrate a flow system directly or indirectly. Direct master meter proving involves the use of a line meter and a master meter connected in series. This type of proving is done at the site of the carrier pipeline.
- Indirect master meter proving will require detachment of the gas meter which will be calibrated at a site remote from its primary location. This requires prover hookups on the relevant metering equipment.
OPERATING OF COMPACT PROVER PROVING SYSTEM
- Compact Prover provides high accuracy, rapid operation, and continuous flow for proving a flow meter in a functional line. This is accomplished without interrupting the normal flow and without the use of manually operated bypass valves.
Operating of Sphere / Pipe prover Proving System
A sphere or pipe prover (which can also be referred to as a ball prover) functions on the principle of constantly replicated displacement of fixed amounts of liquid between two detector devices.When a spherical ball is passed through a calibrated part of piping, a fixed amount of liquid will be displaced. Similarly, within the prover system, an equal amount of fluid will be evacuated. The fluid moved within the ball prover can then be calculated by an attached meter. By this method, the volumes within the pipeline and the prover device can be compared and any variations corrected.
Operating of Prover Tank Proving System
Prover tanks are generally mounted on mobile trailer units that can be pulled by truck from one location to another. The tanks are made of either stainless steel or carbon steel and are designed and built with little or no dimensional tolerances. The use of a prover tank permits the operator to accurately calibrate the accuracy of liquid flow meters.
