The invention discloses an explosion-proof flow rate monitor comprising a droplet conversion device and a signal acquiring and processing device connected with the droplet conversion device, wherein the droplet conversion device comprises a base which is provided with a glass cover and an optical fibre probe; the signal acquiring and processing device comprises a shell which is provided with an optical fibre signal amplification module connected with an input end of a processor module, wherein the processor module is connected with a key module to receive an input signal, an output end of theprocessor module is connected with a signal amplification module connected with a display module, the processor module is connected with an output module, and a power supply module is respectively connected with the optical fibre signal amplification module, the processor module, the signal amplification module, the display module and the output module. According to the property and the frequencyvalue of a droplet, the explosion-proof flow rate monitor can calculate the value of flow rate and meet the relevant regulation of an explosion-proof standard and can be used in a dangerous working environment containing explosive gas.
Description
technical field [0001] The invention relates to an explosion-proof flow monitor, which is an intelligent instrument for on-line cycle detection and control of multi-channel micro flow. Background technique [0002] At present, there are no less than ten kinds of mature flow online detection technologies at home and abroad, such as orifice plate, turbine, electromagnetic, ultrasonic, etc., but none of them are suitable for continuous operation equipment in mining, metallurgy, machinery, energy and other industries. Especially in the dangerous environment containing explosive gas, it is necessary to automatically and continuously add micro-quantity lubricating fluid at each lubrication point, and it is required to monitor the micro-flow in the ultra-thin pipeline on-line to judge the filling status and give an alarm in time. Contents of the invention [0003] The purpose of the present invention is to provide an explosion-proof flow monitor, aiming at the current continuous ...
