Asphalt meter heat meter stainless steel flowmeter

Asphalt, also known as heat meter flow meter for measuring the asphalt flow meter HF50 series metal tube is a measurement of variable area flow meter based on the position of the float, which uses fluid dynamics and magnetic coupling principle, the full metal welding rugged construction and electrical conversion section with HART @ communication protocol can be used to measure different flow requirements of liquids, gases and vapors. HF50 Series metal tube with optional multiple touch liquid material, suitable for most fluid medium; flameproof and intrinsically safe flow meter can be used in hazardous locations; vertical, bottom into the side, the side into the side and horizontal installation suitable for a variety of different forms of on-site installation process requirements. Further, installed in accordance with HART @ communication protocol HF01 meter board in the indicator, users can via a PC or HART @ HART communication protocol, the flowmeter configuration and management, real-time monitoring process variables, different The meter can be realized in the form of the measured flow rate of local indication, remote output, limit alarm and accumulate functions. Well-designed HF50 series metal tube with good precision and reliability, making it to achieve flow measurement and control in complex, harsh environmental conditions and the media over the years in the petroleum, chemical, fertilizer, energy, metallurgy , pharmaceutical, food, water and other fields are widely used. Second, the principle HF50 series metal tube components mainly by measuring tube and indicator components. Measuring tube that has the tapered tube and float straight or tapered orifice and the float, when the fluid flows from the measuring tube by fluid dynamic action, the float will be displaced in the vertical direction, it will eventually float in a stationary position. Area of ??the tapered annular float tube or orifice flow is required at this time. This is a dynamic equilibrium, each fixed flow value corresponds to a fixed annular area, i.e., a unique float position. Position of the float by magnet coupling with a built-in magnet to the pointer indicator within, in the form of non-contact indicates the flow rate value. Through the installation of communication protocol in line with HART @ meter board in the indicator, enabling traffic signal remote output, alarm control and accumulation function.
