Abstract

The invention discloses an air flow differential pressure transmission measurement device, which includes an inner tube, an outer tube, a power supply, a differential pressure transmitter, an intelligent display meter, and a condenser. The special feature lies in: the inner tube and the outer tube It is connected to the condenser, and the power supply is connected to a differential pressure transmitter; the intelligent display meter is used for measuring data, and components are arranged inside the outer tube, and holes for obtaining internal and external pressure differences are arranged on the surface. The invention has small pressure loss, high precision, can still maintain high-precision measurement, is easy to install, does not need too thick or too long straight pipes, has high reliability, is intelligent, and can directly display parameters such as flow rate by a digital instrument, and has a wide measurement range.

Description

Technical field [0001] The invention relates to the field of measuring instruments, in particular to an air flow differential pressure transmission measuring device. Background technique [0002] The currently commonly used steam mass flow meters can only be used to measure the quality of high temperature and high pressure gas. But for superheated steam, wet saturated steam, saturated steam, water, oil and other fluids, especially for the measurement of small pipe diameter, high temperature, high pressure fluid flow, the measurement accuracy is not high and the energy loss is large. Summary of the invention [0003] The purpose of the present invention is to provide an air flow differential pressure transmission measurement device with high flow accuracy and low energy loss. [0004] Another object of the present invention is to provide an air flow differential pressure transmission measurement device. [0005] In order to achieve the above objective, the technical solution adopted ...
