The soap membrane flow meter is suitable for the detection of any gas or liquid flow. The internal microprocessor is combined with the sensitive components to measure and calculate the starting and ending time of the soap film or liquid surface through a volume in the glass tube, and finally calculate the flow rate and visually display it. principle The product combines with the sensitive components through its internal microprocessor to measure and calculate the start and end time of the soap film or liquid surface through a volume in the glass tube, and finally calculate the flow rate and visually display it. Features Its accuracy is much better than the indirect judgment of the eye and handcuffs. The user can measure the gas or liquid flow range from 0.1mL/min to 50L/min by selecting probes and glass tubes of different ranges, and the circuit control unit can realize multi-range conversion and thus has wider use. range. The instrument itself has a calibration function that allows the user to perform self-calibration on site. The operation is convenient and reliable, and all the tested indicators can meet the requirements. how to use 1. Pour soapy water into the latex dripper at the bottom. 2. Use a thin rubber tube to connect the detector outlet to the bottom inlet of the soap flow meter 3. Squeeze the latex dripper to create a soap film and measure the time required for the soap film to flow through a certain volume. 4. Volume can be divided by time. If it is an electronic soap membrane flowmeter, it is convenient to measure and calculate automatically. Technical characteristics National test certificate. The soap film is detected by synchronous pulse width modulation infrared detection technology, and is not interfered by external light. Automatic measurement of ambient temperature, atmospheric pressure. Automatic conversion of standard flow. Dot matrix LCD display, Chinese menu operation. AC and DC, built-in rechargeable high-energy lithium battery. Software parameter calibration. User password protection.
