Höntzsch TA10 sensors use a thin film sensor element using the heat transfer method of flow measurement. This allows the TA10 to measure air velocity as low as 0.2Nm/s. The TA10 thermal flow sensors have a diameter of just 10mm and are constructed from stainless steel, they are easy to install via a 1/2″ BSP fitting, with no moving parts and producing a negligible pressure drop the TA10 gives you a hassle-free installation and long working life. The TA10 can be supplied with just a 4-20mA and pulse output or with an optional Keypad and Display that will allow easy local reading of your flow rate. A WiFi option is also available allowing you to access your setting and flow rates remotely.

TA10 Measuring Uncertainty
Measurement uncertainty for flow velocities Nv with 1014mBar and +21 °C less than/equal to 40 m/s : 2 % of test value + 0.02 m/s greater than 40 m/s : 2.5 % of test value
The TADi is an inline thermal mass meter that is simple to use. Once fitted into your line via the screw connectors, you simply add power (24VDC) The TADi will then give you a 4-20mA output for flow and if available show the flow rates and total on the LCD.
How it works
The Thermal Mass Flow Sensor attempts to achieve a given sensor temperature. As the media passes over the sensor the sensor is cooled. The amount of current needed to maintain the sensor temperature is measured and is proportional to the Flow Rate.
