Industrial Flow Meter Selection

Industrial Flow Meter Selection

Many industrial process control operations require fluid flow measurement as an essential element in the design of the process. The proper application and installation of a flow meter as part of the fluid transfer system will provide accurate flow measurement.

Industrial flow meters use different technologies to measure fluid flow rates directly or indirectly. Some of the most common technologies for fluid flow measurement are vortex flow meters, magnetic flow meters, Coriolis flow meters and rotameters.

Each separate technology has attributes that can make it more suitable for certain applications. The selection of the most appropriate flow measurement technology for an application is an initial and crucial step in the design of a functioning fluid measurement system.

Selection criteria such as fluid temperature, pressure and velocity will be included in the selection process. Further considerations include whether the fluid may be abrasive, corrosive, clean or dirty. The state of the fluid, liquid or gas, must also be taken into account.

The table above provides general guidance on which technologies to consider, based on the above mentioned factors. This will help you to focus further research on product selection.

Contact Classic Controls with any industrial flow application you may have. Their application engineers will provide guidance and advice to assure the proper flow meter is chosen.

Magnetic Level Indicators (MLIs) and Bridle Combination Units

Magnetic level indicators
Magnetic level indicators provide highly visible indication of level with or without signal outputs monitoring tail and vessel level. The term bridle is used to describe a vertical pipe connected to the side of a storage tank or process vessel, most often with side-to-side or side-to-bottom connections. Because the fluid inside the bridle rises and falls equally with the level of fluid inside the tank or vessel, bridles have been adapted for level measurement use on a broad scale.

Yokogawa SENCOM™ for SMART Liquid Analyzer Communications

SENCOM™ technology allows sensors to transmit and receive data when connected to a FLXA202 or FLXA21 transmitter or to any PC with the SPS24 software installed. Yokogawa SENCOM™ SMART is digital communication designed to optimize your process. Digital or SMART sensors maintain specific measurement and calibration data on an integrated chip and an integral part of the sensor. This data can be exchanged between the sensor and either a process transmitter or a laboratory PC using a data management software, like the SPS24.
