Background
The flowmeter, defined by the national committee on the science and technology nomenclature as: meters that indicate the measured flow rate and/or the total amount of fluid in a selected time interval. Simply a meter for measuring the flow of fluid in a pipe or open channel.
When the pressure of fluid passing through the metal tube float flowmeter is unstable, the float in the measuring tube of the flowmeter can generate a bouncing phenomenon, and the bouncing phenomenon is transmitted to the pointer, so that the pointer continuously swings, the flow indication is unstable, and even a scale value cannot be read at all to determine an instantaneous flow value.
In order to solve the problems, a metal tube float flowmeter is provided in chinese patent No. CN 209166539U. In the prior art, when the pressure of fluid passing through a metal tube float flowmeter is unstable, the float in a measuring tube of the flowmeter can generate a jumping phenomenon, and even a scale value can not be read at all to determine an instantaneous flow numerical value. In order to solve the problems, the technical scheme is as follows: including casing, the indicator and the float of being connected with the casing, the casing is inside to be equipped with the toper and to measure the room, and the float is located the toper and measures indoor portion and along with the big or small fluctuation of flow, the shell includes entry flange and outlet flange entry flange department detachably installs the rectifier, the circumference equipartition has a plurality of rectification round holes on the rectifier. The inlet flange is detachably provided with the rectifier, so that fluid entering the flowmeter can be rectified firstly and uniformly enters the flowmeter, the up-and-down oscillation of the floater caused by the sudden change of the fluid pressure is avoided, and the effect of stabilizing the reading is achieved.
The above prior art solutions have the following drawbacks: set up the rectification round hole through having seted up on the rectifier, the inside speed of restriction outside water entering flowmeter to reduce the range of variation of water, but when the inside water of flowmeter is the same with outside water height, the frequency of change of the inside water of flowmeter will become with outside the same, and the float still can be the upper and lower vibrations of high frequency, and measurement of efficiency is low. To this end, we propose a metal tube float flow meter.
