Described low-pressure side flushes film and high-pressure side and flushes film and be connected with differential pressure transmitter respectively by capillary pressure guiding tube, and pressure signal transmission detects to differential pressure transmitter by capillary pressure guiding tube.
According to U.S. FDA certification, require the page backflow dead angle not more than more than 2 centimetres, therefore, described outer casing inner wall is shiny surface, without any projection.
Principle of work of the present utility model is:
On the one hand, liquid is subject to vertical gravitational impact, can produce a static pressure, this force value and fluid density linear, linear with liquid level height, with deposit liquid container transverse width have nothing to do.Liquid in enclosure space, after the static pressure of deduction enclosure space, also presents above-mentioned relation.Therefore, in pipeline, the height of liquid level calculates out by upper and lower pressure reduction.During measurement, the high-pressure side that the low-pressure side simultaneously obtaining top flushes film pressure and bottom flushes film pressure, calculates pressure differential therebetween, and deduction duct static pressure, can draw liquid level in pipeline.
On the other hand, the speed that ultrasound wave transmits in same liquid is balanced, in the process of crosscut fluid, ultrasonic velocity can produce with liquid level flow and deviate, by measuring, determine that on space length, ultrasound wave is transmitted into the two-way time of acceptance, can draw the flowing velocity of crosscut fluid, this method is time difference method.Adopt three groups of ultrasonic measuring devices measuring channel flow rate of liquid respectively in the utility model, signal is sent into main frame respectively.
Main frame is used for signal transacting, and main frame, according to the signal of differential pressure transmitter, calculates liquid level, and then draw current fluid sectional area, then main frame is according to the ultrasonic signal of three groups of ultrasonic measuring devices, after analysis, sampling, ranking operation, draws the flow velocity of liquid.Main frame passes through sectional area and the flow rate information of fluid, can draw the flow volume in actual pipeline.
Advantage of the present utility model and beneficial effect are:
The utility model adopts ultrasonic measurement and flushes film pressure and measure the mode combined and carry out flow measurement, is applicable to plurality of liquid, not the impact of liquid body state, applicability is wide, further, ultrasonic measuring device adopts many group independent measurement interpolation average computation, and measuring accuracy is high.
The utility model structure is simple, meets U.S. FDA authentication specifications, adapts to domestic behaviour in service.
