What are the types of flow meters? Flow meter is a professional automated measuring instrument, whose main function is to measure the flow rate of fluids, including liquids, gases, steam, mixed slurries, solid dust, etc. It is precisely the special role of flow meters that in the field of industrial automation, flow meters and sensors are called the eyes of automation systems. The measurement results are transmitted to the upper computer system, which integrates and analyzes the data, and then applies the preset solutions to the upstream and downstream control systems to achieve intelligent automatic control. Common flow meters include: measuring cleaning liquids such as electromagnetic flow meters, ultrasonic flow meters, vortex flow meters, mass flow meters, orifice flow meters, turbine flow meters, metal rotor flow meters, etc. Measuring gases such as vortex flow meters, V-cone flow meters, orifice flow meters, balance flow meters, waist wheel flow meters (Roots), gas mass flow meters, etc. Measuring steam such as orifice flow meters, vortex flow meters, bend flow meters, etc. Measuring slurries such as electromagnetic flow meters. Users should choose the correct flow meter according to the requirements of the application scenario. Choosing the wrong flow meter will not only affect the project and production, but also cause unnecessary losses to the control system. If you are interested in measuring the flow rate of liquids, you can learn about TSD electromagnetic flow meters, which have high product accuracy and are suitable for various environments.

2. What are the performance characteristics of ultrasonic liquid level sensors?

Ultrasonic level gauges can adopt two-wire, three wire, or four wire

technology. The two-wire system is: power supply and signal output are shared; The three wire system is: the power supply circuit and the signal output circuit are independent. When using DC 24V power supply, a 3-core cable can be used, and the negative end of the power supply and the negative end of the signal output share the same core wire; The four wire system is: when using AC 220V power supply, or when using DC 24V power supply and requiring complete isolation between the power supply circuit and the signal output circuit, a 4-core cable should be used. DC or AC power supply, with 4-20mADC and high/low switch output. The range of the split type ultrasonic level gauge is 0-50 meters, with multiple forms to choose from, suitable for various corrosive and chemical applications, high accuracy, remote signal output, and PLC system monitoring. The working principle of an ultrasonic liquid level meter is that high-frequency pulse sound waves are emitted by an ultrasonic transducer (probe) and reflected back on the surface of the measured material (material). The reflected echoes are received and converted into electrical signals by the transducer The propagation time of sound waves is directly proportional to the distance they travel to the surface of an object The relationship between the distance S of sound wave transmission, the speed of sound C, and the time T of sound wave transmission can be expressed by the formula: S=C × T/2. The probe emits ultrasonic waves, which are then reflected by the liquid surface and received by the probe. The distance from the probe to the liquid (object) surface is proportional to the time it takes for the ultrasonic waves to pass through. HB=CT2, which means distance [m]=time × speed o
