Abstract

The invention discloses a roots flowmeter capable of being used in dark environment. The roots flowmeter comprises a housing. A reading gauge is arranged on the upper part of the housing. The roots flowmeter comprises a stop lever, a guiding block, an illuminating lamp, and a limiting block. The guiding block is arranged on the side surface of the housing from top to bottom. The housing is rotatably provided with the stop lever. The stop lever rotates in a horizontal plane and is abutted against the guiding block, and fixes the guiding block in a vertical direction. The guiding block is provided with a vertical hole. The illuminating lamp comprises a lamp pole and a lampshade arranged on the lamp pole. The lamp pole is arranged in the hole, and can slide along the hole. The limiting blockis under the guiding block, and is fixedly arranged on the lamp pole. The limiting block is provided with a magnet which can be attracted on the limiting block and a touch switch which can control on-off of the illuminating lamp. When the roots flowmeter is used, the magnet is attracted on the limiting block by just pulling the illuminating lamp upward, so that the touch switch is extruded by thelimiting block and is powered on, and the illuminating lamp works.

Description

technical field [0001] The invention relates to the field of flowmeters, in particular to a waist wheel flowmeter that can be used in dark environments. Background technique [0002] A positive displacement flowmeter is an instrument that directly accumulates flow according to the volume of the discharged fluid. It consists of measuring chamber, moving parts, transmission and display parts. Suppose the fixed standard volume of the measuring chamber is V, and the fixed standard volume of the fluid discharged through the flowmeter in a certain time interval is n, then the total volume Q of the measured fluid is Q=nV. The flow rate Q of the measured fluid can be displayed by using the counter to measure the number of revolutions n of the moving parts through the transmission mechanism. [0003] The waist wheel flowmeter is a high-precision measuring instrument used for continuous or intermittent measurement of the flow in the pipeline. It has the characteristics of high prec...
