EDS- Vortex Flowmeter

Vortex flowmeter is working under a Karman vortex street theory, inserting a cylindrical block body in a fluid (liquid, gas or vapor) in the (body vortex occurred), both sides of the block body will alternately swirl, swirl frequency and velocity related. using a piezoelectric sensor or differential capacitance sensor detects vortex shedding frequency, the frequency signal after conditioning, send the microcontroller for calculation processing, it can make the flow of the liquid and the cumulative total of live display, and output proportional to the flow of pulse signal, the current signal, RS-485 communication signals or other communication signals can be used for the flow of liquids, gases and steam measurements. Technical Specifications: Nominal scale diameter: 10-100mm Measuring media: liquid, gas, steam medium temperature: -40-450 ℃ Connection: Fa Lanka mounted, flange, plug-scale public pressure: 2.5Mpa 4.0Mpa Accuracy class: 1.0, 1.5, 2.5 Power supply: 24VDC 3.6 lithium battery output signals: pulse, RS-485 flow rate range: Liquid 0.5-6m / s gas 5-60m / s proof grade: CT4-6 (intrinsically safe type) and a zener barrier supporting the use of protection: IP65 structural forms: ordinary type, intelligent type (with display header)
