In many fields of process and plant engineering liquids or gases play a considerable part in the results of quality control and operational safety. In the case of coolant and lubricant supply, monitoring the functioning of pumps and aggregates, ventilation as well as monitoring the product itself a failure of the flow can cause considerable damage and downtime. Thus it is very important to monitor that these media are at the right place at the right time and in sufficient quantities. Electronic flow monitors based on the calorimetric principle are especially suited for binary flow monitoring.
As these systems work without any mechanically moved parts they can be mounted independent of mounting position and flow direction. Another distinguishing feature of the calorimetric principle is its independence of the viscosity of the medium. Electronic flow monitors are based on the principle of thermal conductivity.
The flow monitor consists of a sensor that converts this physical effect into an electrical signal, and of a control monitor which processes the sensor signals and converts them into a binary signal output. The sensor is mounted directly into the medium. |

Air Flow Sensors Based on the Calorimetric Principle for Air or Gaseous Media. Compact, Precise, Rugged and Reliable
vent-captors are compact, self-contained flow sensors that work according to a calorimetric principle. The principle allows for the creation of compact, reliable flow sensors with a price/ performance ratio not possible with other physical flow-sensing principles.
Especially at a low flow rate, no other sensing principle can achieve the high accuracy of a vent-captor.
First engineered by weber Sensors more than 20 years ago, weber continues to pioneer sensors based on this principle.
vent-captors are available as insertion and in-line types. Both are also available with a binary output as switches and adjustable set-point and with an analog output as meters with an adjustable measuring range. |

The SW-600 series is a range of flow sensors based on the calorimetric measuring principle. This priciple is based on the physical effect that flowing medium absorbs heat energy. The cooling of the sensor tip by the flowing medium is registered and electronically evaluated.
Flow sensors are an essential component of processing- and operation plants in systems technology in order to ensure operational safety. They are used for detection of liqiid media and for coolant supply as well as for operation control at pumps. |

Reliable measurement systems are required for process-related monitoring and control of flow velocity. These must be resistant to environmental influences.

TURCK's wear-free flow sensors reliably monitor the flow of gaseous and liquid media. The calorimetric operation of the sensors is based on the heat transport/heat loss principle, i.e., when fluid moves over the heated sensing probe, heat is conducted away from the sensor. The heat loss is thus a measure of the flow speed.
There are insertion and inline sensors available which can also be used in explosion hazardous areas according to ATEX 100a. Customer-specific versions with regard to special housing designs, materials and connections on request. |

...disturbance insensitive and long-lived!
The turbine flow sensors of the product line Turbotron are sensors for flow rate measurement or dosing applications for liquids. Through its especially compact type, its very wide measuring range and its convincing precision of measurement, it has an almost unlimited application.
Function
The liquid flowing into the Turbotron is divided by the guiding blades in four split beams. These hit the rotor from four directions and put it in motion. The uniform loading of bearing from four sides causes the forces to cancel themselves out for the most part and wear is reduced to a minimum.
The extremely hard bearing materials, sapphire and hard metal, ensure in addition an extraordinary life expectancy.
The rotor rotation rate is now converted into an electrical pulse signal (frequency):
VTH and VTP are equipped with rotors which are fitted with magnets. A Hall effect sensor recognizes the rotation of the rotor.
VTI has stainless steel pins in the rotor. An inductive proximity switch detects the rotor rotation.
In both cases, a flow-proportional frequency signal (square wave signal) is available. |

The CAT3 is a DC or AC powered, microprocessor
controlled transmitter. It outputs a pulse scaled per unit of
flow, and analog signal proportional to flow rate. The
CAT3 can be configured with High and Low alarms. |
