Problems solved by technology

The disadvantage is that when the sizing hole of the gas orifice flowmeter is replaced according to the measured flow rate, the scale 2 should also be replaced with the corresponding scale
Resulting in cumbersome operations, increased preparation time, and reduced measurement efficiency
At the same time, changing the scale will lead to an increase in measurement error

Abstract

The invention belongs to the gas flow measurement technology and relates to the improvement of a ruler for a gas orifice plate flowmeter. A rotary ruler for the gas orifice plate flowmeter comprises a communicating pipe component (1) and an installation support (3) and is characterized by further comprising a rotary ruler body which is composed of a handle (4), a rotary ruler fixing screw (5), an upper positioning sleeve (6), a rotary base body (7), a ruler part (8), a ruler part fixing screw (9), a lower positioning sleeve (10), a handle fixing screw (11) and a washer (12). According to the improved rotary ruler for the gas orifice plate flowmeter, ruler switching is facilitated greatly, switching processes are simplified, measurement efficiency is improved, and measurement errors are reduced.

Description

technical field [0001] The invention belongs to the gas flow measurement technology, and relates to the improvement of the scale of the gas orifice flowmeter. Background technique [0002] The structure of the current gas orifice flowmeter scale can be found in figure 1 , which consists of a connecting pipe assembly 1, a scale 2 and a mounting bracket 3, and the connecting pipe assembly 1 and the scale 2 are fixed on the mounting bracket 3 by screws. Both the display tube and the scale 2 in the connecting tube assembly 1 are in a vertical state. When a liquid column appears in the display tube, read the flow value converted from the height of the liquid column through the scale of scale 2. The disadvantage is that when the sizing hole of the gas orifice flowmeter is replaced according to the measured flow rate, the scale 2 should also be replaced with the corresponding scale. This leads to cumbersome operations, increased preparation time, and decreased measurement effici...
