Kayden's thermal flow and level switch 800 series detects and monitors the flow rate or level/interface of a liquid or gas in a system based on the principle of thermal dispersion or thermal differential. It operates by measuring the amount of heat carried away by the fluid as it flows past a heated temperature sensor, compared to a reference sensor that measures the ambient temperature of the fluid. The difference in temperature between these two sensors is used to determine the flow rate.

Kayden calorimetric flow and level switches, which are often also referred to as thermal flow monitors or level monitors function as follows:

Heating Element
The thermal switch has a heating element (or sensor) that is warmed to a certain temperature above the fluid's temperature.

Temperature Sensors
Alongside the heating element, the device includes temperature sensors. One sensor measures the temperature of the heated element, while another measures the ambient temperature of the fluid or gas.

Flow Detection
When there is no flow or the flow is below a certain threshold, the temperature difference between the heated sensor and the ambient fluid is more significant. As the flow rate increases, the fluid carries away more heat from the heated sensor, reducing the temperature difference.

Detection of Material Level
If the level of the material rises and comes into contact with the heated probe, the probe cools down due to the increased heat dissipation. Conversely, if the level drops and the probe is exposed to air, the probe's temperature rises because air's thermal conductivity is lower, and it dissipates less heat.

Signal Output
The switch translates the temperature difference into an electrical signal that can trigger an alarm, activate a relay, or send a signal to a control system, indicating whether the flow rate is above or below a preset threshold.

Thermal flow and level switches are known for their simplicity, reliability, and the ability to work without moving parts, which minimizes maintenance and the risk of mechanical failure. Flow switches are versatile and can be used in various applications, including HVAC systems, cooling circuits, pump protection (to ensure there is flow in a system and prevent dry running), and process control in industries such as chemical manufacturing, pharmaceuticals, and food and beverage production.

Thermal level switches can be used for level detection in a wide range of applications, including overfill protection, pump protection, and ensuring proper filling or emptying of tanks and containers. These monitors are suitable for use with various materials, including liquids, slurries, and some solids, and can operate in challenging conditions, such as high pressure and temperature environments.

One of the advantages of thermal flow switches is their ability to detect low flow rates and their suitability for use with a wide range of fluids, including liquids and gases. However, their accuracy and performance can be influenced by factors such as fluid properties, temperature, and pressure, so it's important to select and calibrate the switch appropriately for each specific application.
