Flow sensors / flow monitors
Flow sensors, also known as flow monitors or flow sensors, are used to measure the flow of liquids or gases in pipes or ducts. They are used to monitor the flow of liquids or gases, to detect flow rates or to monitor the condition of systems.
There are different types of flow sensors that can be used depending on the application and specific requirements. Some common flow sensor types are
Thermal flow sensors: These sensors measure flow based on heat transfer between a heating element and a temperature sensor. The flow causes a change in temperature distribution which is detected by the sensor.
Ultrasonic flow sensors: These sensors use ultrasonic waves to measure flow. They send ultrasonic waves through the medium and detect the transit time differences of the reflected waves to determine the flow.
Magnetic-inductive flow sensors: Based on Faraday's law of induction, these sensors measure the flow of conductive liquids. They generate a magnetic field in the flow medium and measure the voltage change induced by the flow of the medium.
Eddy current flow sensors: These sensors use eddy currents caused by the flow of liquids or gases. The changes in the eddy current patterns are measured and used to determine the flow rate.
Flow sensors are used in a wide range of applications including the chemical, food, HVAC, water, pharmaceutical and automotive industries.
Modern flow sensors often offer advanced features such as digital displays, communication interfaces and alarm thresholds for integration into monitoring and control systems.
The use of flow sensors enables precise monitoring of the flow of liquids or gases in various applications. They help to optimise processes, ensure efficient use of resources and guarantee system performance.

Types of fluid flow
Laminar flows (layered flow)
Laminar flows occur at a low flow velocity in circular pipes. The fluid moves as a whole in one direction. No turbulence occurs in the fluid. In laminar flows, no significant mixing processes of the fluid occur, since the fluid flows over each other in layers with different flow velocities; there is only a small amount of friction.
Turbulent flows (vortex flow)
In a turbulent flow, turbulent velocity changes occur in the fluid. When the fluid velocity increases, almost any flow becomes turbulent. In turbulent flows, the layers mix. The transition from laminar flow to turbulent flow occurs as a function of the surface roughness of the pipe. The point at which a laminar flow changes into a turbulent flow can be roughly estimated by means of the dimensionless Reynolds number. The flow velocity, density, viscosity of the medium and the characteristic length (e.g. pipe diameter) are included in the determination of the Reynolds number. These quantities determine the type of flow. The Reynolds number at which the transition from laminar to turbulent flow occurs is the critical Reynolds number. As a general statement, a Reynold number smaller than 2320 is a laminar flow, above 2320 a turbulent flow. During the transition from laminar to turbulent flow, the flow resistance of the fluid increases and the velocity decreases.
Flow monitors monitor the flow velocity of fluids. The flow velocity is specified in e.g. m/s, cm/s. If there are deviations between the selected and the measured flow velocity, a switch is actuated or an analog signal is output.
With the help of the flow velocity, the volume flow (flow rate) can be determined mathematically, which is why the flow monitor is also called a flow controller in practice.

What types of flow sensors are there and how do they work?
There are various types of flow sensors, including
1. Thermal flow sensors: These sensors are based on the principle of heat transfer. They consist of a heated element and a temperature sensor. When a fluid flows past, the heat is dissipated by the fluid, which leads to a change in temperature. The flow velocity of the fluid can be measured on the basis of this temperature change.
2. Eddy current sensors: These sensors use the principle of eddy current induction. They consist of a coil through which an alternating current flows. When a fluid flows past, eddy currents occur which change the inductance of the coil. This change can be used to measure the flow velocity of the fluid.
3. Ultrasonic flow sensors: These sensors use ultrasonic waves to measure the flow velocity of the fluid. They consist of a transmitter and a receiver that face each other. The transmitter emits ultrasonic waves which are reflected by the fluid flowing past. The flow velocity of the fluid can be calculated based on the transit time and the frequency shift of the reflected waves.
4. Magnetic-inductive flow sensors: These sensors are based on the principle of magnetic induction. They consist of electrodes that are arranged perpendicular to the direction of flow. When a conductive fluid flows past, a voltage is generated that is proportional to the flow velocity. This voltage can be used to measure the flow velocity of the fluid.
These are just some of the most common types of flow sensors, but there are also other specialized sensors that have been developed for specific applications.

What attributes should be considered when selecting a flow sensor?
When selecting a flow sensor, various attributes should be taken into account:
1. Measurement range: The flow sensor should cover the desired measuring range, i.e. be able to detect the flow velocity that will occur in the application.
2. Accuracy: The accuracy of the flow sensor is crucial for the reliability of the measurement results. The more accurate the sensor is, the more precise the measurements can be.
3. Response time: The response time indicates how quickly the sensor reacts to changes in the flow. The faster the response time, the more accurately rapid flow changes can be detected.
4. Pressure loss: The flow sensor should cause as little pressure loss as possible so as not to unnecessarily increase the energy consumption of the application.
5. Temperature range: The flow sensor should be suitable for the intended temperature range to ensure reliable measurements even at extreme temperatures.
6. Material compatibility: Depending on the application environment, it may be important that the flow sensor is made of corrosion-resistant materials or is resistant to certain chemicals.
7. Mounting and connection options: The flow sensor should be easy and safe to install and have suitable connections to enable smooth integration into the system.
8. Costs: The cost of the flow sensor should be in proportion to the benefits and requirements of the application. It is important to find the right balance between cost and performance.
These attributes can vary depending on the application and specific requirements. It is therefore advisable to contact a specialist or manufacturer before selecting a flow sensor in order to determine the best options for the application in question.

How are flow sensors calibrated and maintained?
The accuracy of flow sensors is usually checked by calibration and adjusted if necessary. Calibration can be carried out either on site or in a specialized calibration laboratory.
During calibration, the output signals of the flow sensor are compared with known flow values. For this purpose, the sensor is used in a controlled test setup that enables the flow velocity to be measured precisely. The values measured by the sensor are then compared with the reference values and corrected if necessary.
The maintenance of flow sensors usually includes regular cleaning and inspection of the sensor and, if necessary, the replacement of wearing parts. Cleaning is usually carried out by rinsing with special cleaning solutions to remove deposits or impurities. The purpose of the inspection is to detect any damage or signs of wear and tear and to take appropriate repair measures.
It is important to observe the manufacturer's instructions for calibration and maintenance, as these may vary depending on the sensor and application.

1. Thermal flow sensors: These sensors use a heater and temperature sensors to measure the heat loss caused by the flow. The higher the flow rate, the greater the heat loss.
2. Ultrasonic flow sensors: These sensors use ultrasonic waves to measure the flow rate. They send ultrasonic waves into the flow and measure the time it takes for the sound to travel from the transmitter to the receiver. The flow rate is calculated using the transit time difference.
3. Eddy current flow sensors: These sensors use an electromagnetic field to measure the flow rate. When a conductive liquid flows through the sensor, it generates eddy currents that influence the magnetic field. The change in the magnetic field is measured and converted into a flow rate.
Various measurement errors can occur when using flow sensors, e.g:
1. Calibration error: Flow sensors must be calibrated in order to provide accurate measured values. If the calibration is not carried out correctly, measurement errors may occur.
2. Installation error: Correct placement of the flow sensor is important in order to obtain accurate measured values. Incorrect installation or positioning can lead to measurement errors.
3. Influences of temperature and pressure: Changes in temperature and pressure can influence the measuring accuracy of flow sensors. It is therefore important to take these factors into account when measuring.
4. Pollution: If the flow sensor is dirty, this can lead to incorrect measured values. It is important to clean the sensor regularly to maintain the accuracy of the measurement.
5. Aging: Over time, flow sensors can lose their accuracy. Regular inspection and, if necessary, replacement of the sensor is required to ensure accurate measured values.
It is important to consider the specific requirements and potential sources of error for each application to ensure the best possible measurement accuracy.
