Coriolis flowmeter (straight tube type) is a new type of flow measurement instrument based on the principle of Coriolis force, which is a straight tube sensor structure. It can directly measure the mass flow rate of fluid and the density of medium in a closed pipeline. A flowmeter consists of two parts: a flow measurement sensor and a signal converter. Being able to directly measure the mass flow rate of fluids (which is of great significance for energy metering and production process detection and control such as chemical reactions).

Characteristics of Coriolis flowmeter (straight tube type)

1. High measurement accuracy (measurement accuracy can be guaranteed to be between 0.1% and 0.5%).
2. The measurable ratio is generally 10:1 or 20:1 to ensure basic accuracy.
3. Widely applicable, in addition to normal fluid measurement, it can also measure industrial media that are difficult to measure with general fluid measuring instruments, such as high viscosity fluids, various slurries, suspensions, etc.
4. It can measure parameters such as density and temperature of the measured medium online, and derive the concentration of solutes in the measured solution based on this.
5. The installation requirements are not high, and there are no specific requirements for the upstream and downstream straight pipe sections.
6. Reliable operation and low maintenance rate.

Installation of Coriolis flowmeter (straight pipe type)

1. The installation of CMF mass flowmeter sensors should ensure that the flow direction identification of the sensor is consistent with the fluid flow direction.
2. The Coriolis mass flowmeter is a flow meter measured based on the principle of measuring tube vibration. Therefore, when installing the sensor, it is necessary to consider providing strong support for the relevant pipelines to avoid vibration of the instrument and related pipelines.
3. If strong pipeline vibration is unavoidable, it is recommended to use flexible pipes to isolate the pipeline system from instrument sensors.
4. During installation, the flange faces should be parallel to each other, so that the centers of the two flanges are on the same axis to avoid additional stress.
5. When measuring liquid flow, the fluid should be directed from bottom to top as much as possible, and the instrument should be avoided from being installed at a high point in the pipeline to prevent gas accumulation in the pipeline from affecting the normal operation of the instrument.
