LZZ metal rotor flowmeter adopts variable area measurement principle, which is suitable for measuring liquid and gas. All-metal structure, there are indicator type, electric remote transmission type, corrosion-resistant type, high voltage type, jacket type, explosion-proof type. With 0-10mA, 4-20mA standard analog signal output and on-site instructions. Accumulation, digital communication, field modification of measurement parameters, different power supply functions, with magnetic filters and special specifications. Widely used in petroleum, chemical, power generation, pharmaceutical, food, water treatment, etc. During the process of flow measurement under complex, harsh environmental conditions, and various media conditions.
