Product Name: Spiral Double Rotor Flow Meter

Product Code: HDFF

Application scope:
Spiral rotor flowmeter is the latest product in the field of volumetric flowmeter. The measuring part is a pair of spiral rotors with special tooth shapes, which are used for measuring and controlling liquid flow in pipelines.

characteristic:
Precise design and professional craftsmanship, with extremely high precision and repeatability;
Double rotor spiral structure design, contactless rotation, uniform displacement, smooth operation, low vibration and noise;
No need for straight pipe sections, accuracy is not affected by fluid flow conditions, and it can adapt to a wide range of medium viscosity.
