PID controllers and pitot tubes are also used for this. The exact measurement of the smallest differential pressures is crucial for the cost-effective and technical monitoring of room air systems. Air flow sensorsįor the monitoring of air flows in ventilation and air-conditioning systems, flow sensors are suitable for volume flow calculation based on the measured differential pressure and the fan constant (K factor) of the connected radial fans. Corrosion-resistant materials enable applications in areas such as the chemical industry, machine building, the pharmaceutical industry and in medical engineering. A float activates a reed contact as soon as the flow rate exceeds a preset value. Calorimetric flow switches are also known as thermal flow monitors and are ideal for monitoring coolant circuits or for controlling filter units.įlow monitors do not need any power supply and work on the float measurement principle. Furthermore, the design of these flow meters allows exact monitoring of the temperature without the need to set up an additional measuring location. The flow rate can thus be calculated on the basis of the temperature difference. The temperature difference that occurs due to the cooling effect of flowing media is measured here. The FSD-4 flow switch is based on the calorimetric measuring principle. Laboratory analysis of SF 6 & alternative gasesĮlectronic flow switches offer the operator a local display of the flow values and at the same time an output of an electrical signal (PNP, NPN or 4-20 mA) for transmission to a remote control room. Flow meter merupakan alat ukur yang sudah tidak asing lagi bagi sebagian orang khususnya yang sering bersinggungan dengan pekerjaan konstruksi bangunan.Basic materials (minerals, metals, paper).Valves with integrated pressure regulators.Heat transfer and distribution stations. Laboratory analysis of SF6 and alternative gases.International service network with system calibration.Power transmission and distribution (SF 6).Precision pressure measuring instruments.
