The MFS thermal flow sensor can be used in a wide flow range from 0 to 150 m/s (CTA mode) and in a temperature range from -40 °C to +80 °C. It is used for flow measurement of a wide variety of gases. A special feature of the MFS sensor is that it is also suitable for industrial flow applications with smoke or exhaust gas development. IFM Flow Sensors. Flow switches & transmitters can be used to monitor the flow of liquid through a pipeline for example coolant or lubrication to ensure that if the flow rate falls or the supply is cutoff warning can be given before damage is caused to equipment. Return to IFM electronic sensors at Seltec. The system is available with one discharge flow sensor or multiple discharge flow sensors. When a single sensor is installed it is mounted on the pump discharge manifold. It provides an input signal directly to the control module that is proportional to the discharge flow. Systems with multiple discharge flow sensors require a summing box. Each Monitor's Solids Flow Detector and Indicator can be used in a variety of applications to detect flow/no-flow conditions of powders and solid materials. The selection of either SFD-2 Solids Flow Detector or the SFI Solids Flow Indicator is based upon the type of output required (relay or analog). Can use the flow sensor with an input power supply of from 12 to 24 VDC (permissible voltage fluctuation ±10%). The amplifier protection structure conforms to IP67. Can set the lower limit of the flowrate. If the flowrate falls below this limit, the red LED lamp (NG) turns on, and contact Siargo Mass Flow Sensors. Siargo offers a wide range of off-shelf mass flow sensors to serve today's increasing demands of flow measurement, monitoring and control in energy, medical, food & beverage, machinery, environmental and many other industries. Flow Sensor Modules, Flow Meters, Liquid and Gas. Flow sensors, also known as flow meters, are used to measure the flow rate, and ultimately the total volume, of gases or liquids passing through module's pre-determined cross sectional area. These measurements are critical in a broad range of Flow sensors SI5000 Flow monitors SID10ABBFPKG/US Compact type for adapter Plug and socket 1: LED display, 2: setting pushbutton Application liquids and gases Electrical design DC PNP Output normally open / closed programmable Operating voltage [V] 1936 DC Current rating [mA] 250 Short-circuit protection pulsed Reverse polarity protection yes Supplier, manufacturer, dealer, distributor of Siemens SITRANS FM MagFlo MAG 5100W Electromagnetic Flow Sensors and Siemens Flow sensor Data Manual, Data Sheet, Price & Delivery There are two answers, if you have an old non-using microphone, you can just use the microphone to instead of flow sensor. Or on the other hand, you can choose the pizeo sensor, which can detect vibration of ambient environment, and behave as a changing voltage.
