Flow rate volumes of gases – an important parameter in industrial processes
Actions to save energy and to assure quality in the production process are of particular importance in industrial processes. The ability to measure volumetric flow rates and volumetric flow of gases precisely is essential for this purpose. The requirements imposed on the flow rate sensor used for this are demanding: the sensor has to be capable of delivering precise measuring results for different gases, at high overpressures and across wide ranges of temperature. It also has to be able to do so under the most difficult environmental conditions. A further decision factor is the prevention of maintenance and its attendant high secondary costs. Simple assembly and reliable measuring values for many years are expected.
The “true professional“ for industrial processes and compressed air technology
The thermal SCHMIDT® Flow Sensor SS 20.700 is the perfect solution for extremely demanding industrial applications. It can be used for a diverse range of applications, such as compressed air monitoring, gas monitoring on process burners, consumption recording of gases and a great deal more.The double-pin sensor head has been designed to meet the needs of so-called „heavy-duty applications“ and, due to the sensor elements being completely encapsulated in stainless steel these are ideally suited for extremely demanding applications such as the generation of biogas and the like. The sensor is also resistant against aggressive media.
The SS 20.700 records flow speed as well as media temperatures up to 120 °C. It can be used in small tubes starting from DN 40 upwards and involve a sensor length up to 600 mm to measure the volumetric flow rate in large channels and ducts. The sensor can be used in overpressure up to 16 bar. This sensor is very easy to install: screw in the sensor using the compression fitting included, align the sensor in the gas flow and centrally in the pipe, connect it electrically – ready!
This sensor operates without any moving parts and employs a measuring principle that eliminates any drift or signs of ageing. This reduces the maintenance required for the sensor to an absolute minimum.
High gas speeds or special gases? The SS 20.700 can do both!
The sensor with its special double-pin sensor head records flow speeds of 0.1 m/s up to 220 m/s. In order to obtain precise measuring results across this very broad speed range, every sensor is individually checked and compared in an elaborate pressurized wind tunnel. To enable this sensor to be used in different gases, a range of individual versions are available, e.g. for pure oxygen, nitrogen, argon, CO2 and more.Specification
