The MICRO-Flow sensor is a flow detecting device, used within a semi or fully automated metering process, to detect whether material has been dispensed.
The MICRO-FLOW Sensor does not control the metering volume. It is used particularly when handling unfilled grease with NLGI class 1 to 3, high viscosity oils or silicone-oils.
The MICRO-FLOW Sensor can be adapted to the DOPAG Micro and Mini metering cock as well as to the 417 range of the measuring valves.

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 displays 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 professional 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. |

FLOW RATE SENSOR fluid-Check (FOR HYDRAULIC OIL)
Examples:
Monitoring flow rate and wear of pumps
Operability of accumulators
Professional filter transmittance
Suppliers of heat exchangers
Nozzle suppliers flow rate
Speed of suppliers of hydraulic motors
Description:
Via a hole in the pipe (plastic deformation with the measuring supplier of connector serv-Clip® Type 2), the sensor is placed directly into the oil circuit. The measuring system is based on the calorimetric principle, measuring flow rate speed in Meter/Second. Inexpensive and rapid Mounting. Durable and compact design.
It can be combined with measuring connector serv-Clip® Type 2 ( for mounting on non-pressurized pipes ).
Installation ONLY 3 Minutes, NO NEED TO CUT PIPES www.servclip.com
You can measure in several points with ONE sensor but for each tube you need the measuring connection serv-Clip.

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 detection 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. |

TURCK's wear-free manufacturer of flow sensors reliably professional 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. |
