Прямое измерение массового расхода. ±0,1% до ±0,2% для жидкостей ±0,5% для газов Измерение плотности, температуры, давления Широкий диапазон регулирования до 100:1
Почему объемные расходомеры прямого вытеснения могут использоваться для топлива и масел? Измерение объемного расхода топлива или масел относится к дизельному топливу, топливу на нефтяной основе, керосину, печному топливу для дома, реактивному топливу, диз
Кориолисовый расходомерэто идеальный выбор измерение расхода мазута Кориолисовый расходомер обычно состоит из трубки для измерения расхода и двух датчиков, которые измеряют силы Кориолиса, создаваемые жидкостью при ее протекании через трубку. Силы Кориолиса прямо пропорциональны массовому расходу мазута, что позволяет получать высокоточные и надежные измерения.
Расходомеры мазута способны измерять широкий диапазон скоростей потока, от очень низких до очень высоких, и могут работать с различными марками и вязкостями мазута. У нас есть множество типоразмеров датчиков массового расхода на выбор, диапазон расхода от 1 грамма/час до 1000 тонн/час. небольшой датчик расхода размеры от 1 мм до большой расходомер масла например, 10-дюймовые расходомеры масла. Они также рассчитаны на работу в суровых условиях, типичных для промышленных предприятий, таких как: датчик массового расхода масла при высоких температурах расходомер высокого давления, химический расходомер для коррозионных жидкостей, измерение расхода мазута под высоким давлением. измерение высоковязкого мазута .

1. The coriolis mass flow meters are working based on the vibration working principle. So it is the best that there will be no vibration on the installation place. And the strong support of the installation pipelines of the coriolis mass flow meters is very import. If the vibration cannot be ignored, it is suggested to use the soft tube connection. And the connections pipelines and the mass flow meters should be on the same axis. Please do not add additional force on the mass flow meters, other wisethe accuracy of the mass flow meters might be affected.
2. If the percentage of the gas in the measured oil fuel is high, then it is a must to install the gas- liquid separation tank on the inlet of the coriolis mass flow meters.
3. The throttle devices, for example the flow control valves should be installed on the outlet of the mass flow meters.
4. The mass flow meters should be installed away from the outlet of the pumps. Especially for the Dual pumps, if the installation distance is too close, then the measured flow rate could be affected, which is fluctuated.
5. If measuring high temperature oil or it is required to keep warm of the measured oil, Please keep distance between the inner tubes of the heating jackets or the heating tubes with the housings of the sensor. We factory also provide the heating jackets along with the mass flow meters, for example the heating jackets for steam or transfer oil. Please specify that you need heating jacket for flow meters to silverinstruments.com
6. The measured oil should be on the suitable flowing status. If under the local environment the flowing status of the liquids is not suitable, then it is suggested to improve with other methods, for example to modify the temperature of the liquids ( increasing / decreasing the temperature of the fuel oil to make sure the measured liquids are in the proper flowing status.
7. Installation direction: please make sure the flowing direction of fuel oil should be the same with the direction marks on the nameplates of the coriolis mass flow meters. Otherwise the accuracy of the mass flow meters could be affected.
8. Please make sure the series numbers of the mass flow transmitters and the fuel oil flow sensors are one -to-one corresponded to each other. It cannot be easily changed. Otherwise the accuracy of the mass flow meters could be affected.
9. If the fuel oil mass flow meters are installed on the outdoors, then it is the best to install the rain shelters for the mass flow meters. And please make sure to keep both the front and back covers of the mass flow meters tightly closed. And please make sure that the electrical interface is sealed well to prevent the waters flowing inside the transmitters.
10. It is suggested to use the normal working flow rate higher than the 1/3 of the standard flow range of the mass flow meters. And it is suggested that the actual minimum flow rate should be higher than the 1/10 of the standard flow range of the mass flow meters. If it is in special situation, please communicate with silverinstruments.com, As we have our own R&D team, we can customize the mass flow meters based on your own special requirements, to make sure that we can meet with the requirements of the users of the usage range.
The integration of the Coriolis Mass Flow Meter has been connected and installed before the delivery.
The separated transmitter and the sensor are connected by the special connection cables and connectors. If the separation installation of the transmitter and the sensor is required, please contact us in advance before placing the order. The maximum length should not exceed 300m.

The zero point calibration is required after the Coriolis Mass Flow Meter installation. Please fill in large amount of measured medium for 10 minutes before the zero point calibration.
The zero point calibration is used to provide the benchmark of the flow measurement. The zero point must be processed after the first-time calibration or re-installation. Please make sure firstly it is required to turn off the stop valve at the exit of the mass flow meter, and then turn off the stop valve at the entrance. And make sure the liquid fulfilled the sensor is comparatively at the stationary state during the calibration. The detailed operation methods are as below video shows:
Trouble shooting for Coriolis flow meter
Symptom | Failure Reason | Solution |
No display | Check whether is 24VDC power supply is normal | Make sure 24VDC is working normally |
Fluctuation of flow rate measured is large | Whether there’s strong vibration of the line connected to the sensor | Adding support or switching to hose connection |
Could not enter the measuring interface after the boot | Do not connect with the sensor | Check the cables, and make sure they are connected to the sensor properly |
Zero Point Drift is large | The installation of the sensor has stress | The connecting line and the sensor interfaces should be at the same axis |
Attention: (0-10)KHz and (4-20)mA output signal is already with the power supply. It is forbidden to connect with other external power sources. Otherwise the damage of the mass flow meter could be caused.
