1. What do GPM and LPM mean on a glass rotor flowmeter?
GPM and LPM on a glass rotor flowmeter are both flow units. GPM stands for gallon per minute, which means gallon per minute. LPM stands for liter per minute. The conversion relationship between GPM and LPM is: 1 gallon (US)=3.785 412 liters. So the conversion relationship for flow rate per unit time is: 1 GPM=3.785 LPM. Working principle of glass rotor flowmeter: When the fluid passes through a conical glass tube from bottom to top, a pressure difference is generated between the upper and lower parts of the float, and the float rises under this pressure difference. When the upward force, buoyancy, and viscous lift acting on the float are equal to the weight of the float, the float is in an equilibrium position. Therefore, there is a certain proportional relationship between the fluid flow rate flowing through the glass rotor flowmeter and the rising height of the float, that is, the flow area of the glass rotor flowmeter. The position height of the float can be used as a measure of flow rate. Additional information: Glass rotor flowmeter can be applied in various fields such as metallurgy, power, coal, chemical, petroleum, transportation, construction, textile, food, medicine, agriculture, environmental protection, and peoples daily lives in the national economy.
2、 Environmental protection engineering: To control air and water pollution, it is necessary to strengthen management, and the basis of management is quantitative control of the amount of pollution caused by spinal curvature.
3、 Pipeline transportation: Pipeline transportation must be equipped with flow meters, which are the eyes of control, distribution, and scheduling, as well as

4、 Biotechnology: There are many substances that need to be monitored and measured in biotechnology, such as blood, urine, etc.
5、 Scientific experiment: The flow meters required for scientific experiments are not only numerous, but also extremely diverse in variety. According to statistics, a large part of the over 100 types of flow meters are for scientific research purposes. They are not mass-produced and are sold on the market. Many research institutions and large enterprises have set up dedicated teams to develop specialized flow meters. Reference source: Baidu Baike - Glass Rotor Flow Meter
2. Flow Unit of Float Flow Meter
The flow unit of Float Blue Orange Mingzi Flow Meter is divided into two categories: volume flow unit and mass flow unit. The actual selection needs to match the medium type, operating parameters, and calibration standards
1. Volume flow unit (the most mainstream measurement scenario of float flow meter) 1 International standard universal units: The most commonly used units in domestic industrial scenarios include m ³/h (cubic meters per hour), L/min (liters per minute), mL/s (milliliters per second); For gas media, it is necessary to clarify the operating conditions: Nm ³/h (standard cubic meter per hour, corresponding to the commonly used 20 ℃ and 101.325kPa standard atmospheric conditions in China), and some scenarios will be marked with m ³/h (working condition) to distinguish the volume flow rate under non-standard conditions. 2. Common units used in American engineering: mostly used for export equipment or foreign old production lines, commonly referred to as gpm (American gallon per minute) and
