The mass flow meter produced by our company can well solve the difficult to measure fluid problems, such as high temperature, low temperature, high pressure, high viscosity, small flow, large temperature and pressure fluctuations, user requirements, fast response time, high accuracy requirements and other actual measurement needs .
U shape coriolis mass flow meter
U-tube Coriolis flowmeter can measure the lowest temperature -200 ℃, such as the measurement of LNG. The highest temperature can reach 350 ℃, and the highest pressure can be measured at 100MPa.
The mass flowmeter consists of a sensor and a transmitter. The mass flow meter is equipped with digital signal processor (DSP) -based digital transmission equipment, and integrates digital closed-loop vibration control (DLC) signal processing, sensor calculation and diagnostic functions, and has high measurement accuracy and extensive capabilities. And excellent reliability for you. On-line node configuration, fault diagnosis and data logging can be performed directly through HART or PC via Modbus to communicate with the communicator. The flow meter will not only calculate the process volume flow, cumulative volume and component ratio. TS series flow meters can also provide mass flow, density and temperature online in real time.
Product introduction
Coriolis mass flow meters are the most accurate measuring method in the world. The Coriolis measuring principle is used in a wide range of different branches of industry, such as the life sciences, chemicals, petrochemicals, oil and gas, food, and- no less importantly - in custody transfer applications. Coriolis flowmeters can measure virtually all fluids: cleaning agents, solvents, fuels, crude oil, vegetable oils, animal fats, latex, silicon oils, alcohol, fruit solutions, toothpaste, vinegar, ketchup, mayonnaise, gases or liquefied gases.
The Sincerity DMF series U-shape is the standard high performance coriolis mass flowmeters for the process industry. The U shape bent tube meter offers superior performance and high accuracy in virtually any application. From process control in (petro) chemical applications to concentration measurements in the food and beverage industry to custody transfer filling and transport measurements in the oil and gas industry. Its high-end options also make the DMF-1 Series U-shape the optimum device for cryogenic media like Liquefied Natural Gas (LNG) with temperatures down to -200°C / -392°F as well as applications involving high operating temperatures (up to 350°C / 662°F) or pressures (up to 1000 barg / 14504 psig).
Each Coriolis flowmeter has one or more measuring tubes which an exciter causes to oscillate artificially. As soon as the fluid starts to flow in the measuring tube, additional twisting is imposed on this oscillation due to the fluid’s inertia. Two sensors detect this change of the tube oscillation in time and space as the “phase difference.” This difference is a direct measure of the mass flow.
In addition, the fluid density can also be determined from the oscillation frequency of the measuring tubes. The temperature of the measuring tube is also registered to compensate thermal influences. The process temperature derived from this is available as an additional output signal.
