- Characteristics : Wide range----range proportion1:120 (exceptional1:1000)。Minimum flow rate is 0, Maximum flow rate could reach to 60m/s。intelligentialize----adopt the latest smart chip appeared at abroad In recent years, liquid crystal display with double row sixteen digits. Mass flow measurement----temperature and pressure are not needed for compensation, can measure and display the flow of gaseous mass or standard. Lower flow rate measurement----upper limit flow rate could be 0.5m/s, lower limit is 0. Display on-site----accumulated mass flow or standard cube flow, instantaneous mass flow or standard cube flow, flow percentage. Setting on-site----suited for all occasions, automatic identification and revise on-site according to different composition gas.
The basis of good flow meter selection is a clear understanding of the requirements of the particular application. Therefore, time should be invested in fully evaluating the nature of the process fluid and of the overall installation.
- What is the fluid being measured by the flow meter(s) (air, water, etc…)?
- Do you require rate measurement and/or totalization from the flow meter?
- If the liquid is not water, what viscosity is the liquid?
- Is the fluid clean?
- Do you require a local display on the flow meter or do you need an electronic signal output?
- What is the minimum and maximum flow rate for the flow meter?
- What is the minimum and maximum process pressure?
- What is the minimum and maximum process temperature?
- Is the fluid chemically compatible with the flow meter wetted parts?
- If this is a process application, what is the size of the pipe?

Thermal flow meters measure mass flow rate by means of measuring the heat conducted from a heated surface to the flowing fluid. Relying on the principle that a fluid flowing past a heated temperature sensor removes a known quantity of heat as it passes, thermal flow meters measure either how much electrical power is required to maintain the temperature of the heated sensor or the temperature difference between the heated sensor and the flow stream. Either of those values is directly proportional to the m
