1. Product Introduction:

       YYF-H intelligent float flowmeter consists of two parts: a sensor with metal structure and a flow indicator. The sensor part includes a flange-connected measuring tube (one-time formed cone tube or built-in orifice plate), float, and upper and lower stops. It is used to measure the single-phase flow of liquid, gas and steam in closed pipelines. It has the characteristics of simple structure, convenient maintenance, high reliability and wide applicability. Widely used in flow measurement and process control in petroleum, chemical, electric power, metallurgy, medicine, food, light industry and other industrial sectors, as well as water treatment and other fields.

       One-time formed cone tube technology, streamlined tube design, small pressure loss; CIV, DIV, E type float shapes optional, suitable for different working conditions; Backlight display, 4-20mA two-wire current output; The converter is far away from the tube body, which can meet the measurement of medium below 350℃.

2. Product Features:      

       One-time formed cone tube, streamlined tube design, small pressure loss;

       Using complementary bilinear magnetic field sensor, thus improving the adaptability to field working conditions;

       CIV, DIV, E type floats are available for different occasions, the float rotates freely to achieve self-cleaning function;

       Dual power supply hardware design;

       4-20mA two-wire backlight display;

       Self-rectifying lower stop design for higher measurement accuracy;

       Pointer type, LCD display converter head explosion-proof design;

       Modular combination design, convenient maintenance, maintenance-free under normal use;

       The magnet is made of Nd-Ni-Co material, which can be used for high-temperature medium measurement, with maximum medium temperature resistance of 350℃

Using high-temperature sensor with strong high-temperature resistance.

3. Industry Applications:
