Flow Meters

Flow meters are used to measure the volumetric or mass flow rate of a liquid or gas. Yokogawa's range of flow meter instruments include vortex, magnetic, variable area, Coriolis, and differential pressure flow meters.

Overview:

Accurate and durable magnetic flow meters (magmeters) were difficult to maintain in the process as the corrosive and abrasive nature of the process degraded their operation. That led to leaks that not only reduced the flow but also contaminated the product and the magmeters. Since Sigura maintained strong vigilance, the company needed to replace some magmeters monthly...

Overview:

In the food and beverage industry, government regulations for whisky production require compliance of distillation strengths to strict limits. Yokogawa’s ROTAMASS TI Coriolis mass flowmeter is well-matched for the application with its density calibration for ethanol or water percentage and a special calibration for maximum accuracy and stability. The mass flow meter’s dual bent tube technology and advanced software enabled the customer to measure the very small and sensitive range required. Yokogawa commissioned the mass flowmeter onsite to ensure the correct installation and commissioning from the outset, affording Total Insight through the entire product lifecycle.

Overview:

Yokogawa’s ADMAG TI - AXG magnetic flowmeter (magmeter) with EtherNet/IP is used to measure the water moving from the pump to the snow cannons. The accurate measurement allows the operator to monitor and control the water in the mixture to produce artificial snow with the perfect consistency.

Overview:

The reliable accuracy of the AXG magmeter is a result of Yokogawa’s proprietary, dual-frequency excitation method, which combines traditional high/low-frequency excitation methods to ensure greater stability and quicker response even if noise or other problems are present in the line. The customer was very pleased with the result, as it allows him to automatically mix yogurt with cherries, which was previously impossible due to the measurement deviations.

Application Note
Overview:

If the customer could accurately measure the essential oil concentration, then the heat/steam could be adjusted to the correct levels. Increasing the efficiency of the process and saving money.

Overview:

A milk tanker is typically fitted with a pump and flowmeter that records the volume of milk loaded from each individual farm. Confirmation of the total volume of milk delivered to the dairy plant is performed either by weighing the tanker or via flowmeters in the tanker bays.

Overview:

Brewers recognized that correcting flowmeter inefficiencies in out-of-date technology would help them achieve the increased and consistent throughput they needed. 

Industries:
Overview:

The condiment facility staff had success with Yokogawa’s ADMAG TI AXG magnetic flowmeters in other applications. When they learned EtherNet/IP communication was now offered on the ADMAG TI - AXG, they chose to use the Yokogawa magmeter solution on the mustard grinding lines.

Industries:
Overview:

The Coriolis flow meter has many features such as direct measurement of mass flow and measurement of fluid density, which other flow meters do not support. Therefore, since being introduced for practical use in the late 1970s, its market has rapidly expanded in many industries such as oil, chemicals, and foods.

Yokogawa Technical Report
Overview:

Vortex flow meters were put into practical use in the 1970's; thus their history is relatively short. They have been mainly used at petrochemical plants because of their two main features, the fact that they do not have any mechanical moving parts and are maintenance-free. Yokogawa started research and development on the vortex flow meter before 1970.

They help remove stray energy or noise as it builds up in the flow process by grounding it. They can even help protect the magmeter liner from damage in harsher processes.
