1. Alcohol specific flowmeter elliptical gear flowmeter selection table
In order to choose a suitable alcohol specific flowmeter, we first need to consider key parameters such as the flowmeter model, nominal pressure, viscosity and temperature of the measured liquid, and flow range. The following are several main model selection tables, corresponding to flow meters of different materials (cast iron type, cast steel type, stainless steel type), in order to meet different usage needs. Model and nominal pressure: - Cast iron type (A): nominal pressure is 1.0 Mpa, 1.6 Mpa. -Cast steel type (E): nominal pressure is 2.5 Mpa, 4.0 Mpa, 6.4 Mpa. -Stainless steel type (B): nominal pressure is 1.0 Mpa, 1.6 Mpa. Viscosity and temperature of the tested liquid: - viscosity range: 2-200 mPa. s. -Temperature range: -20 ℃ to+100 ℃. Flow range and accuracy level: The flow range corresponding to the model and nominal diameter is as follows:- DN0.5: 0.4 m³/h - 0.4 m³/h - DN0.2: 0.1 m³/h - 0.4 m³/h - DN10: 0.4 m³/h - 0.4 m³/h - DN15: 0.15 m³/h - 1.5 m³/h - DN25: 1 m³/h - 6 m³/h - DN40: 2.5 m³/h - 15 m³/h - DN50: 4 m³/h - 24 m³/h - DN65: 5 m³/h - 40 m³/h - DN100: 10 m³/h - 100 m³/h - DN150: 32 m³/h - 190 m³/h - DN200: 34 m³/h - 340 m³/h By comparing the parameters provided in the above table, you can choose the appropriate alcohol specific flow meter model according to your actual needs. For example, if your application needs to withstand high nominal pressure and flow requirements within a specific range, then cast steel type (E) or stainless steel type (B) would be the ideal choice. At the same time, considering the viscosity and temperature of the measured liquid, ensure that the selected flowmeter can adapt to these c

2. How to choose a flow meter when measuring liquids?
When selecting a flow meter for measuring liquids, it is necessary to consider the characteristics of the medium, measurement parameters, installation conditions, and functional requirements, and match them with the applicable scenarios of different types of flow meters. The specific selection steps and applicability of various types of flow meters are as follows:
First, clarify the core parameters. Users need to provide the following parameters to narrow down the selection range: medium type: conductivity, corrosiveness, cleanliness (such as water, ammonia water, sewage, chemical raw materials, alcohol, deionized water, etc.). Physical properties of the medium: temperature, density, viscosity (affecting fluid fluidity and flow meter response). Pressure range: Flow meters with pressure resistant design should be matched for high or low pressure environments. Flow range: minimum flow, common flow, maximum flow (determining flow meter range and accuracy). Pipeline diameter: The flowmeter needs to match the pipeline size to avoid installation issues. Functional requirements: Power supply mode (such as 24V DC, battery power), output signal (such as 4-20mA, pulse, etc.) RS485）、 Display requirements (on-site display or remote monitoring), measurement accuracy (such as ± 0.5%, ± 1%). Installation environment: whether there is electromagnetic interference, vibration, high temperature or corrosive ga
