Who can recommend some flowmeters for measuring low flow rates at low velocities?
Thread Content
The flow rate is between 0 and 0.1 m/s; please provide the specific model selection, and it would be best to have samples available
Pipe diameter and medium? 0.1 m/s is indeed too low; considering reducing the diameter might be an option. For low-flow rate measurement, a mass flow meter can be considered; however, it is relatively expensive ； Positive displacement flow meter ； Ultrasonic flowmeters, etc.
Pipe diameter and medium? 0.1 m/s is indeed low, so the Reynolds number is also low; it may be necessary to use a specially designed laminar flow meter. Typically, differential pressure types (such as those with built-in orifice plates), float (also known as rotor) types, volumetric types, and thermal mass flow meters are used for measuring very small flow rates.
What is the caliber? For low flow rates, you can use rotors; if precision is required, mass-based methods can be used. Our company deals in products of imported quality
Are there any requirements? Should it be sent over a long distance? Do not use glass rotors for long-distance transmission; also, avoid using the small-orifice plates used in laboratories for measurements that require precision. If cost is not a concern, go for higher-quality options
