Problems solved by technology

[0003] In the prior art, after the initial setting of the glass rotameter, if the pressure value in the glass tube is high or low due to changes in the pressure of the gas source or the flow rate of the stopped gas exceeds the process range, and the pressure value in the glass tube has not been restored for a long time. Normal value, it is very easy to cause safety accidents, and even endanger personal safety in severe cases

Abstract

The invention provides a glass rotor flow meter with an automatic alarm function. The glass rotor flow meter comprises a flow meter body. The flow meter body comprises a conical glass tube and a floatarranged inside the conical glass tube, the conical glass tube is provided with a maximum flow scale A and a minimum flow scale B, a position detection device for detecting the position of the floatis installed outside the conical glass tube, and an alarm is further connected to the position detection device. When the position detection device detects that the position of the float is lower thanthe minimum flow scale B or higher than the maximum flow scale A, an alarm signal is sent to the alarm, and the alarm receiving the alarm signal can ring and give an alarm so as to remind a worker ofpotential safety hazards. Accordingly, the glass rotor flow meter with the automatic alarm function is good in safety, and accidents can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of instruments and meters, in particular to a glass rotameter with an automatic alarm function. Background technique [0002] The main measuring element of the glass rotameter is a vertically installed tapered glass tube with a small bottom and a large top and a float that can move up and down in the tube. When the fluid flows through the tapered glass tube from bottom to top, a pressure difference is generated between the upper and lower sides of the float, and the float rises under the action of the pressure difference. A float is in equilibrium when the upward force, buoyancy, and viscous lift are equal to the weight of the float. Since there is a certain proportional relationship between the flow rate of the fluid flowing through the glass rotameter and the rising height of the float, that is, there is a certain proportional relationship between the flow area of ​​the glass rotameter and the rising heig...
