Liquid Flow Regulator: Everything You Need To Know About Them

The liquid flow regulator measures the water supply for commercial and domestic use. And its primary purpose is to restrict fluid output to a specified flow rate. These controllers are self-cleaning, and they maintain an accuracy of 15 percent of the valves Gallon Per Minute (GPM) for pressure drops. And 125 PSI for pressure up.

In essence, this product can measure and control the flow rates of liquid-based samples. These controllers can work for applications that need a constant flow rate and compensate for different pressure changes. So, unlike the flow meters, which precisely measure the flow rate, liquid flow controllers measure and control, making them valuable products. And due to this functionality, it explains the price difference between the two products.

Functions Of Liquid Flow Regulator
Liquid flow controllers use a suitable control valve and flow rate sensor to regulate the flow rate despite inlet pressure fluctuations. So, it receives liquid through an inlet where the fluid passes via a high resistance liquid flow path whenever the pressure drops. As this happens, the pressure sensor will measure the liquid flow amount and quickly generate the pressure drop signal. It’s a signal fed in an electronic circuit.

And there will be a valve that regulates the flow of liquid in the downstream path of the high-resistance liquid flow. And this monitors the flow-driven by an error. Before it generates the error signal, first, the electronic circuit will create a viscosity-normalized flow signal. And it compares this to a set point.

While working with the IRIDIUM Series Liquid Flow Control System, the user gets an option to assign a setpoint by using a touchscreen monitor on this device. But he can also use it remotely via an electronic signal. And the liquid flow regulator will adjust the integrated valve accordingly, depending on the desired flow rate.

And this is a great feature that allows the user to operate the flow controller using various settings and positions. A user can use the flow rates, the state of the alarm, totalized flow, and much more from the integrated touchscreen.

A liquid flow regulator works best for applications that need micro-low flow rate measurements. So, the control will apply in cases with a constant flow rate. These flow controllers are also used in the semiconductor industry.

Various applications for McMillan’s IRIDIUM Series Liquid Flow Control System include:
Sample the liquid flow rate regulation
On-demand chemical dilution
Monitoring and regulating the consumable usage
In essence, liquid flow controllers are an excellent choice if you have a product that requires measuring and regulating flow rates. More of these benefits include; automated compensation for pressure changes, touchscreen operation, or remote and versatile use across several applications.

Mass Flow Controller
This type of liquid flow regulator measures and regulates the flow of gasses and fluids. These MFCs come in a standardized design to control certain types of liquid and gas at a specific flow rate. An MFC operates well in the 10-90% range, though you can set it to 0-100%. But in this range, you can achieve the best percentage of accuracy. That means the MFC can control the flow rate at the scope of this given setpoint, and this device can either be digital or analog.

While the analog controllers have a standardized liquid limit, digital MFC flow controllers can control more than one type of liquid.

All MFCs have a flow sensor, control valve, outlet, and inlet port. How do these operate? An operator enters an input signal which he uses to compare the value from the flow sensor. So, this adjusts the proportional valve needed to get the preferred flow rate.
These MFCs are used in a range of industrial applications. And the top ones include the following:
LED production tools $ semiconductor fab,
Biopharmaceuticals
Chemical gas
Petrochemicals.
As you can see, this flow control equipment is handy in various industrial applications. Each plays a critical role in a specific application.

Top Benefits of Liquid Flow Regulators
One of the working benefits of a liquid flow controller is it automatically compensates for changes in many pressure settings. These depend on a set point given by the operator, and the compensation allows for a controlled and stable flow rate.

High accuracy and repeatability are the other benefits that IRIDIUM Series Liquid Flow Control System offers. So, it provides repeatable flow measurement because of the miniature PTFE microturbine wheel suspended on a sapphire shaft. Due to the zero-friction design, they provide a fast response and don’t generate any particles.

It’s critical to ensure you’re using compatible liquid flow regulators with other fluids. For instance, the IRIDIUM Series Liquid Flow Control System includes wetted materials of only PTFE, Viton, and sapphire that ensure compatibility.

An ideal liquid flow controller is always reliable, dependable, and serviceable. If a user uses the IRIDIUM Series liquid flow controller, it allows an operator to swap modules or change a fitting without going to the factory. This modular design allows for one flow controller use for multiple ranges and configurations.

In Conclusion
With these nuggets of knowledge, you should now understand what a is and why it can be helpful in various applications. Flow controllers can measure and control fluid flow, unlike flow meters. That only tells you that they are more versatile and convenient. However, these may be a bit pricier than the flow meters, though they are efficient to work with, as they save time and speed performance. In addition, accuracy, repeatability, and compatibility are all vital features to look out for when purchasing these controllers.
