Description

Flowmeter with movable flange plate

Technical Field

The utility model relates to a flowmeter, in particular to take flowmeter of mobile flange dish.

Background

With the development of science and technology and the application of new achievements, the types of pipeline flowmeters are changing day by day. More than ten types of commonly used pressure difference flow meters, volume flow meters, turbine flow meters, vortex flow meters, impeller flow meters, variable area flow meters, electromagnetic flow meters, ultrasonic flow meters and the like are adopted. Although various pipeline flow meters have commonality, more of the various pipeline flow meters have characteristics of the various pipeline flow meters, such as measurement range, flow rate variability, measurement accuracy, installation conditions, requirements on water flow quality and the like. Therefore, the use conditions and requirements are comprehensively considered and selected by combining the characteristics of various flowmeters, so that the purposes of applicability, economy and convenience are achieved.

The general waste water has more impurities, large sand content, large temperature change and corrosiveness, and is not suitable for a turbine flowmeter, a vortex street flowmeter, a differential pressure flowmeter, a positive displacement flowmeter, an impeller flowmeter and an ultrasonic flowmeter, and the measurement precision can be influenced. And more commonly a variable area flow meter. A floating member of the variable-area flowmeter, which is arranged in a tapered flow passage with a large upper part and a small lower part, moves under the action of fluid flowing from bottom to top. When this force is balanced with the "apparent weight" of the float (the weight of the float itself minus the buoyancy of the fluid to which it is subjected), the float is at rest. The height at which the float is at rest can be used as a measure of the magnitude of the flow.

The bolt holes of the flange plate and the bolt holes of the external pipe fitting are difficult to align during installation of the existing variable-area flow meters, great inconvenience is brought to installation steps, and time and labor are wasted during installation. In addition, when some current variable area formula flowmeters use, the liquid flow is disorderly in the body, and the float part vibrates easily, sends the noise, influences measuring degree of accuracy and precision, and the result of use is poor.
