What are Standard Liquid Flowmeter?

Do you do business or deal with substances like air, liquid, or gases? To monitor their flow rates is one thing you won’t avoid. With improved technology, you can measure the flow velocity of fluids with ease. All you need is a flowmeter.

But what is a flowmeter? It’s just a device that helps you measure and determine the flow rate of liquid or gas, which moves through a pipe. You can use a flowmeter to measure the quantity of fluid passing via pipe within a given time. But other flow meters measure the total amount of gas or fluid that has passed via a flowmeter.

A flowmeter has three main parts. You will find the primary device, transducer as well as transmitter. Once the fluid you seek to monitor pass through the primary device, a transducer can sense it. A raw signal from the transducer is sent to the transmitter to inform a readable flow signal.

Do you want to buy a flowmeter? They are of different kinds. Besides, they work in different ways. But all of them achieve a similar goal though they work in different ways. All of them will, at all times, help you measure the flow rate with accuracy.

Standard types of flow meters

  1. Electromagnetic flowmeter

Just like the name suggests, this device determines the flow rate through a magnetic field. Magnets form the magnetic field within the pipe through which the fluid you want to measure flows. With the support of that fluid’s conductive elements, the magnetic field can change the fluid’s voltage. That change in voltage helps you to measure the flow rate. This device is most suited to measure water-based liquids.

  1. Pressure flowmeter 

There is dynamic pressure or differential pressure that helps to determine the flow rate. In differential pressure, the pipe is limited to lower the pressure. If you increase the fluid further, the pressure will go up. But how do you get the flow rate using differential pressure? Just look at the pressure change created between the inlet as well as the outlet valve.

In dynamic pressure, you will have to find the difference between points. That’s where pressure is static and where the liquid you want to monitor has zero viscosity. That way, you can find the flow rat with ease.

  1. A mechanical flowmeter

You will find different kinds of mechanical flow meters. But they help to measure the flow rate of substances through internal mobile parts. They may pass an isolated and known quantity of fluids via a series of chambers or gears. But they may help get flow rate by way of the spinning rotor of the turbine.

Every PD flow meter operates via isolating and counting a known volume of a liquid. That fluid feeds it through a meter. If you count the number of knowns and passed isolated volume, you get the flow rate. Each PD design uses different ways to isolate and calculate the fluid quantity. Then, the pulse train frequency will help you find the flow rate.

Do you want to buy this liquid flow meter? You will have to carry out a close check. The mobile parts of this device can be affected by particles carried by the fluid. They can cause damage and affect the useful function of your flow meter.

  1. Ultrasonic flowmeter

You can use this device to measure any fluid without stress. It has a clamp-on version snapped outside the pipe that carries the fluid you seek to measure. The ultrasonic flow meter uses ultrasound to measure the volume of flow. It has ultrasound transducers that measure the average flow rate along a path of the emitted beam. It averages the changes in measured passage time. That’s between pulses of the ultrasound spreading into and against the flow direction.

  1. A vortex flowmeter

It has a flow sensor that senses pressure changes. There is a vortex- shedding by the liquid in the passage. So, the device adjusts pressure change into a flow sensor signal. The flow signal comes to inform of the electrical signal. The signal processor will then receive the flow sensor signal. It creates an output signal that matches the pressure change from vortex-shed.

The fluid you are monitoring flows via the bluff body at a specific speed. An alternate vortex belt set is formed at the back of the bluff body sides. The two sides of the vortex generator form a vortex in an alternating way. So, the pressure pulses are built on the two vortex generator sides. That will make the detector to form alternating stress.

The electric feature condensed in the direction probe body will create an alternating charge signal. That signal has a similar frequency to the vortex within the action of the alternating stress. The frequency of the pulses is relative to the flow rate. A signal will then be sent to the intelligent flow totalizer. It is then processed. But it has to be amplified by pre-amplifier.

Conclusion

Monitoring the flow rate of substances has become easy. Just get a flow meter, and you will measure the flow rate without hassle. You will find different flow meters in the market. While they work in different ways, they will help you attain one goal. That is to determine the rate of fluid flow. Ensure to get the right standard flow meter.

That way, you will avoid losses that may come from a wrong application. Note that not all kinds of flow meter are compatible with all types of fluids. You should consider the size of the pipes, material, and impurity of the liquid before purchasing a flow meter. Also, keep in mind the viscosity of your fluid.
