The Coriolis Effect is the operating principle for Micro Motion Coriolis mass flow meters, and it’s important to understand when researching flow measurement. Before describing the theory of operation, I’ll discuss the technology advantages from both a process and business perspective, and give an overview. Whether for liquid, gases or slurries, Micro Motion Coriolis mass flow technology offers many advantages over traditional volumetric flow technologies such as positive displacement meters, orifice plates and turbine meters. The benefits include:
- Lower capital expenditures by using a multi-variable measurement device that provides direct, precision measurement of mass flow rate, density and temperature
- Improved process uptime and flexibility through high reliability, a wide range of operation, and bidirectional flow capability
- Improved product quality and tighter process control through higher accuracy and repeatability resulting in reduced waste, rework and scrap
- Reduced cost of installation, since there are no special mounting, flow conditioning, or straight pipe runs required
- Reduce maintenance costs because there are no moving parts, no calibration drift, and no need to adjust the factory zero in typical operating conditions
- Simplified work practices with Smart Meter Verification to confirm the meter components are operating correctly without disrupting the process or trips into the field
- Measurement accuracy for gases, fluids with entrained gas and slurries
The Overview So what exactly is a flow meter?
Figure 1.
A Micro Motion Coriolis flow meter’s (Figure 1) main components are a sensor and a transmitter. The sensor detects the fluid properties and operational parameters such as flow rate, density and temperature, while the transmitter processes the sensor signals and transmits the measurement information to a control system for process control, process monitoring, or fiscal transaction validation. Peripheral devices can be connected to the transmitter to provide enhanced capabilities such as batch control and receipt printing for fiscal transfer tracking.
Some of the common fluid measurement applications include loading/unloading, container filling, blending, dispensing, concentration monitoring and batching.
I’ll dig deeper into how Coriolis meters work and provide a cost comparison between Coriolis meters and traditional flow technologies in my next post. Stay tuned!
