Electronic Flow Controller Features Explained

Introduction of Electronic Flow Controller (EFC)

EFC is an electronically controlled regulator that provides excellent repeatability over a wide flow range. It features a fast flow response time and a higher flow rating than do mechanical flow controllers. The EFC can be used in automatic control, high resolution and repeatability applications where count-by-count control is necessary.

Because the EFC is an electronically controlled regulator, the opening of the control valve has been increased to provide faster response times. The EFC is ideal for use in critical applications where count-by-count control is necessary.

Its high resolution and accurate repeatability make it ideal for use in critical applications where count-by-count control is necessary.

The EFC's high resolution and accurate repeatability make it ideal for use in critical applications where count-by-count control is necessary. Examples of critical applications include:

• Chemical process systems requiring extremely precise mixing or dilution rates, such as those used in the semiconductor industry.
• Food processing plants where precise amounts of ingredients are added to each batch, such as chocolate manufacturers.

EFCs are also used in non-critical applications, such as water treatment plants that require consistent measurement of flow rate over time periods longer than a day but not on the order of years or decades (as would be required for nuclear power plant cooling towers).

It also features a fast flow response time and a higher flow rating than do mechanical flow controllers.

The Electronic Flow Controller (EFC) is a high-tech, electronically controlled regulator that provides excellent repeatability over a wide flow range. The EFC has a faster response time than mechanical flow regulators and offers greater rangeability. The remote display indicates both the actual and setpoint values in real time. It also features an auto-lock feature to prevent accidental movement of the knob when transporting or storing your machine.

Automatic control, high resolution, high repeatability, compatible with air/water/oil

Before we get into the important details of what makes an Electronic Flow Controller (EFC) different from other types of flow controllers, let's look at some of the benefits that make it an attractive choice:

• Automatic control - Your EFC does not require manual adjustment. Once set up and programmed, it runs on its own to provide consistent and accurate process control.
• High resolution - You can program a full range of values from 0% to 100%. The resolution will depend on your device, but typically they have up to 8 bits worth of precision (256 possible settings). This means you can fine-tune your system with extremely accurate measurements at very low flow rates or high ones; anywhere in between is no problem either!
• High repeatability - With any kind of controller, repeatability refers to how closely two successive measurements will correspond with one another over time as long as input conditions remain constant. For example, if you were using a manual valve for open/close control instead and wanted 20 mL/min flow rate adjusted by hand every second based on some meter readings from upstream or downstream equipment (you would do this because manually adjusting valves is easier than programming instructions into a computer), then each successive measurement would result in slightly different values because there would be human error involved each time--maybe someone accidentally moved their finger too fast when setting up their positioner valve housing! But once again we're talking about automatic control here...and if your EFC has been configured properly then every value should match up perfectly every single time regardless how many times per second data needs updating via PLC communication link!

Features

The EFC is fully automatic, with a high resolution and high repeatability for stable and accurate control. It is compatible with air/water/oil users have the option to select the best working fluid for their application.

Low cost, easy to use electronic flow controller

The electronic flow controller is a low-cost, easy-to-use device that can be used in any application where it is necessary to control the flow of fluid through a pipeline. It works by measuring the pressure drop across its sensing element and then transmitting this information back to your controller via an analogue signal. The device uses very little power and has no moving parts, making it ideal for environments where space and reliability are at a premium.

Higher resolution

The EFC is capable of providing a flow control resolution of 0.1% of the full-scale flow rate, or 1% of the full-scale flow rate. In addition, the EFC provides closed loop proportional control that can be commanded from 0% to 100%. The minimum step size is 0.1% (or 1%) of full scale for proportional control and 0.01% (or 1%) for integral action.

Faster response time

• A faster response time means that the EFC can respond more quickly to changes in flow, which can be critical when it comes to medical applications.
• Better repeatability and higher resolution means that the EFC can more easily maintain consistent flow rates over time with less drift.

Better repeatability

Repeatability is the ability to reproduce a value multiple times. Repeatability is a measure of how well a process can be reproduced and it's important for manufacturing and quality control, as well as scientific research. For example, if you are trying to test whether your new sunscreen blocks UV rays or not and you want to determine whether it works by measuring how much UV light passes through the solution, you would need to have consistent measurements in order for them to be useful.

Greater rangeability

In a mechanical controller, there is always some flow loss. This is due to the pressure drop that occurs in the control valve and piping from the pump. In contrast, an EFC can control flow within one percent accuracy with no pressure drop. Additionally, EFCs have a faster response time than their mechanical counterparts because they use electrical signals rather than pneumatic ones to open and close valves (which require power).

Conclusion

The Electronic Flow Controller (EFC) is a high-tech, electronically controlled regulator that provides excellent repeatability over a wide flow range. Automatic control and high resolution make it ideal for use in critical applications where count-by-count control is necessary. Its fast flow response time also makes it ideal for high flow applications such as cooling towers and process water systems. The EFC has been approved by the factory for use with air/water/oil based fluids at pressures up to 100 psi and temperatures up to 400°F (204°C).
