BVW type multi-channel conductivity probe bubble parameter meter Introduction: The BVW2 multi-channel conductivity probe bubble characteristic parameter measurement instrument uses two conductivity probes arranged at a certain distance to measure the local conductivity value inside the reactor. Based on the significant difference in conductivity between gas-liquid phases, it can accurately reflect the gas phase (bubble) change process at its location. It is used to measure the local gas content, bubble size distribution, bubble velocity distribution, interface concentration and other bubble characteristic parameters in gas-liquid two-phase flow. The entire equipment consists of a BVW2 multi-channel bubble characteristic parameter measurement instrument host, 4-8 conductivity probes, signal cables, and application software. Features: 1. The product size is small and has little interference with the flow system 2. The instrument can connect 4, 8, or 16 probes simultaneously, and can measure 4, 8, or 16 measurement points simultaneously in real time 3. Each channel is equipped with excitation level and level offset adjustment functions, with adjustable sampling frequency (500Hz-20kHz) and sampling data volume 4. The system software functions include: raw data collection and display; Real time or playback display of voltage time curves for each channel; Save voltage time data for each channel, calculate and save the average voltage and threshold voltage, bubble average velocity, velocity extremum, bubble velocity distribution, bubble content, bubble average diameter, diameter extremum, and diameter distribution for each channel; Can be set and saved, including sampling frequency, sampling data amount, probe spacing, and sampling channel window, etc; The saved data files can be opened by Notepad and Excel software; The application measurement software can run in a Windows environment. 5. Online measurement, real-time data display, raw data, calculated bubble velocity, diameter distribution, etc. can be provided with statistical results through histograms, lists, curves, and other methods Technical parameters: Instrument models: BVW2-4, BVW2-8, BVW2-16 Applicable environment: Conductivity 100-2000 μ S/cm of clean water; Normal temperature, not exceeding 60 ° C; Pressure less than 0.1MPa; If it contains solid particles, only when the average particle size is<150 μ s. Used when the solid content (volume) is less than 10% Measurement range: Bubble flow rate<1 m/s, bubble size approximately 2-30 mm Measurement method: Contact based online measurement Probe size: Standard probe measuring end face diameter 5mm, probe measuring section length 400mm Note: Customized conductivity probes of different specifications can be used to measure bubbles under different conditions
