Product Description
The crude oil mass flow meter employs the Coriolis Principle
(Coriolis Force) to directly measure the "Mass" of the medium with
exceptional accuracy. Unlike traditional flow meters, its precision
remains unaffected by factors such as temperature, pressure,
density, viscosity, and others.
This eliminates the need for compensation calculations. The
Coriolis Mass Flow Meter comprises two main components: the Sensor
and the Transmitter. Notably, it is designed and manufactured in
compliance with national explosion-proof standards, ensuring safety
and reliability in potentially hazardous environments.
Principles of Measurement
The Coriolis Mass Flow Meters consist of a pair of curved tubes in
their structure. The operational principle involves detecting the
Coriolis force that results from fluid flow forcing the pair of
tubes.
The appearance of a new force, the Coriolis force, is contingent
upon two conditions being met: firstly, the tubes vibrate at their
normal frequency, and secondly, there is a flow of fluid within the
tubes. This force emerges as a synthesis of the vibrating force and
the flowing force caused by the fluid within the tubes. The force
compels the tubes to twist symmetrically around the center line.
Two displacement sensors positioned on the sides of the tubes
detect the force and generate electric signals. These signals are
then regulated, and the direct output is the mass flow measurement.
In essence, the Coriolis Mass Flow Meters operate by leveraging the
Coriolis force induced by fluid flow through a pair of vibrating,
curved tubes to accurately measure mass flow.

Model Selection Principle:
In the applied fields of Coriolis Mass Flow Meter, the Max. Flow
rate is determined by pressure loss, while the Min. Flow rate is
influenced by measuring accuracy.
Before selecting the product, the client or user should refer to
the manual and provide relevant data such as accuracy, flow rate,
pressure loss, density, viscosity, temperature, etc., for correct
size selection and application.
