How to Use Liquid Flow Sensors and Its Advantages
Liquid flow sensors are commonly known as flowmeters. They are devices used to measure the flow of liquids. They also measure and regulate gases and steam in the pipes. The sensor can detect blockage, leaks and changes in fluids as well.
Flow measurement is essential in many industries. Therefore, you should always make sure you use the right meter for the correct application. Flow sensors have devices such as transducers and transmitters. The transducer helps in sensing the fluid passing in the primary device. The transmitter will then receive the signal from the transducer. This signal changes into a flow signal. Always make sure to choose the right meter for your application.
Liquid Flow Sensors and Its Advantages
Venturi Liquid Flow Sensor
Venturi flowmeters are used to measure a large amount of fluid at low-pressure drops. These meters are able used to find the flow measurements in a straight pipe. Venturi tubes work in such a way that the liquid is increased over the joining cone. The throat is then measured, and it gives the signal for the flow rate.
The pressure recovery for this sensor is better than that of the orifice place. Venturi sensors have low pressure and are fit for clean water, dirty and thick fluids. This meter can recover energy and has high pressure, which makes it suitable for small pressure heads.
Advantages of Venturi Sensors
- Venturi flow sensors have no energy differences, and their pressure drop is low.
- This meter is also the best because it is easy to maintain and install
- Also, they are used to measure clean, dirty and thick fluids.
Magnetic Flow Sensors
Magnetic flow sensors are one of the most popular meters around. They use Faraday’s law of electromagnetic induction. The law says that when the conductor moves over a magnetic field, energy is created. The liquid should conduct electricity to create a magnetic field.
The energy created is directly related to the flow rate. These meters are as well used to measure corrosive and slurry fluids.
Advantages of Magnetic Flow Sensors
- Magnetic flow sensors do not have moving parts. So, they cannot wear, and their maintenance is easy and cheap.
- These meters are not affected by changes in temperature, the thickness of the liquid or electrical conductivity.
- Magnetic flow sensors are not affected by contaminated liquids because they have no moving parts.
Ultrasonic Flow Sensors
Ultrasonic sensors work using ultrasonic waves. The waves can pass through solids, liquids and gases. The features of the waves are then used to determine the fluid flow in the tube. Then the ultrasonic signal is sent to the line at an angle. You will then measure the time taken for the call to travel from one side to another. The time difference between the pipe and the signal is directly related to the flow rate.
Advantages of Ultrasonic Flow Sensors
- Ultrasonic flow sensors do not have moving parts. Therefore, they will not wear out, which makes them easier to maintain.
- Also, they have no added pressure drops and measure reactive liquids.
Coriolis Flow Sensors
Coriolis meters are the most popular meters in the world. It is because they have high accuracy levels and are common in large industries. Coriolis meters measure the mass of the liquids. And are not sensitive to temperature, pressure, thickness and density changes.
The sensor is used to determine the flow rates of liquids, slurries and gases. They are also used in industries such as; biochemical, Medicine, mining, wastewater and oil and gas industries.
Advantages of Coriolis Liquid Flow Sensors
- They have high accuracy measurements and are not affected by the fluid’s temperature, pressure, or density.
- Coriolis sensors measure accurate mass flow
- They measure flow in both directions
Vortex Liquid Flow Sensors
Vortex sensors are also referred to as oscillatory flowmeters. These meters use the natural thing where liquids flow in a fake object. The vortex shedding speed is directly related to the velocity of the fluid flowing over the tube. These meters are mostly used to determine the flow rate of steam.
Advantages of Vortex Meters
- Vortex meters are best for measuring the flow of liquid, gases and steam.
- They are also not affected by pressure, temperature and density changes in the fluids.
- These meters are also the best because they have no moving parts. So, they will not wear, making them cost-effective.
- Their accuracy levels are too high, and you can install and maintain them easily.
