Description
1. Coriolis Flow Meter Product Overview
The KNKE Coriolis Flow Meter (straight tube type) from the USA adopts a straight tube sensor structure, designed based on the principle of Coriolis force. This new type of flow measurement instrument can directly measure the mass flow and density of fluid in closed pipes. It consists of two main components: the flow measurement sensor and the signal converter. The Coriolis flow meter is highly effective for accurately measuring fluid mass flow, which is of great significance for energy metering and process control in chemical reactions.

8. Coriolis Flow Meter Installation Guidelines
- Installation Direction: Ensure that the KNKE-CMF flow meter sensor is installed in line with the fluid flow direction.
- Support Requirements: Since the Coriolis flow meter operates based on vibrating tube technology, provide sturdy support for the sensor and related pipelines to avoid any vibrations that could affect measurement.
- Vibration Isolation: If strong pipe vibrations are unavoidable, use flexible pipes to isolate the sensor from the piping system.
- Flange Connection: During installation, the flange surfaces should be parallel, with the centers of both flanges aligned on the same axis to avoid additional stress.
- Installation Position: When measuring liquid flow, try to ensure that the fluid flows from bottom to top, and avoid installing the instrument at the highest point in the piping to prevent gas accumulation, which may affect measurement accuracy.
