Product Description

Features
1, Long service life with MTTF of 25 years.
2,High-quality steel frame with negative electrophoresis treating on its surface
3,High stable magnetic bearing and self-lubricating graphite bearing.
4,The rotor shaft and worm is turned integrative to ensure proper mesh.
5,Very small mutual influence among three adjustment points: full-load, slight-load and phase. Customers can adjust the meter easily for their own demands.
6,Flat metrological characteristics curve and small variation against to voltage, frequency, temperature, and operating position. Good consistency for batch production.
