Conical body pressure tapping flowmeter

Abstract

A cone pressure tapping flow meter relates to the field of flow meters; a pressure tapping device is provided with a negative pressure tapping pipe; a positive pressure tapping pipe is arranged before the negative pressure tapping pipe; the positive pressure tapping pipe and the negative pressure tapping pipe are connected with a differential pressure transducer; the front side of the pressure tapping device is provided with a cone, and the rear side is provided with a frustum cone; the cone pressure tapping flow meter has the advantages of good current stabilizing performance, small pipe resistance, high flow, small pressure loss, high efficiency, small energy consumption, high stability of the discharge coefficient, high measuring precision, low manufacturing and use cost, applicability to measurement of the flow of all fluid media, in particular to measurement of all high-temperature dirty media which contain impurities and are easy to crystallize, such as coke oven gas, blast furnace gas, etc.

Description

technical field [0001] The invention relates to a flowmeter, in particular to a cone pressure-taking flowmeter. Background technique [0002] As we know, the existing flowmeter is equipped with a ring-type pressure take-off on the inner diameter of the pipeline. The inner side of the ring-type pressure take-off is an acute angle. There is a positive pressure-taking tube in front of the tube, and the positive and negative pressure-taking tubes are connected to the differential pressure transmitter to calculate the fluid flow. This kind of flowmeter, because there is a ring-type pressure taker on the inner diameter of the pipeline, the ring belt of the ring-type pressure taker blocks the pipeline, the pipeline resistance is large, the flow rate is low, the pressure loss is large, the efficiency is low, the energy consumption is large, and the use cost High; because there is a ring-type pressure gauge on the inner diameter of the pipeline, when the liquid flows through the rin...
