A vortex sensor refers to a flow meter that follows a linear relation with the volume flow rate. It is widely accepted compared to other sensors. That is because it has no square-root relationship. Vortex flowmeter assesses the right amount of flow of a fluid. Do you wish to know if you have any leakages in your pipe? Well, vortex flow got you sorted. The flow meter works under the vortex shedding principle. Below are some of the types of vortex flow meters.
Ultrasonic meter flow
Ultrasonic meter flow has a right turn down ratio. Behind the bluff body lies the ultrasonic transmitter and a receiver. A vortex adjusts the ultrasonic beam. That results in the array of the vortex signal. The cons with the vortex sensor are that the sound sources can affect the value.
A capacitative sensor is a device that feels nearby objects by their effect on the electrical field from the flow meter. On the side of the bluff body, it has welded stainless steel barriers. The capacitance is inversely related to the distance between the electrodes. It also refers directly to the plate area. They are found in various designs.
Capacitive sensors can always adjust the sensitivity. That fixing is made by changing the potentiometer. If there is a rise in its sensitivity, it leads to a lot of sensor effects. If you wish to deal with con-conductive targets, check out the factors below;
- The surface area of the target object
- The size of the active site of the flow meter
- The dielectric constant
Those three factors will affect the sensing stretch. Dirt or heat can trick the sensor. The benefits of using the Capacitative sensor are;
- Have shock-free output signal
- They fit flexibly to housing shape.
- Capacitative sensors are contact-free
- You can remove them with ease
- Have foam and deposit amends
Mechanical flow meter
The mechanical sensor is also known as the shuffle ball sensor. It relies on the law of the mechanical twisting of a tool that turns into an electrical signal. A magnetic disc moves on all sides as a result of whirls. A magnetic pickup feels that motion. But, the steam can slow the ball motion.
Thermal flow meter
We all use thermal flow meters in our day to day tasks. These are tools used to measure the degree of hotness or coldness of a fluid. The thermal sensor uses a voltage across the diode terminals’ law. A thermal sensor has two main types. They include; contact sensors and non-contact sensors.
Piezo electronic sensors are one of the most used types of vortex sensors. It is used to sense the pressure swing within the bluff body. These flow meters feel the vortex shedding. That is made possible by the use of force applied to the shedder bar. The sensor has a piezo element. The element offers a voltage output relative to the pressure applied. The lithium niobate piezoelectric matter provides an output medium only. Yet, there is an intense heat limit to the strain gauge.
Strain gauge sensor
It has a body bluff that creates a vortex. That vortex causes the shift of the body itself. Strain gauges placed directly or indirectly to the bluff body dig up the stretching motion. The strain gauge sensor’s main hitch is the intense heat of the 120°C strain gauge.
As we have seen, there are many types of vortex flow. The query is, how do you pick one? Well, there are few factors to look at before choosing a flow meter. They include; the type of fluid, pressure, pipe size, among others. Ensure you make the right choice when it comes to picking a vortex flow. All the best!
