Product Desciption
Product Overview:
HFM400 Metal tube float flowmeter (metal tube rotor flowmeter) is a kind of variable area flowmeter commonly used in industrial automation process control.It has the characteristics of small volume, large detection range, easy to use, it can be used to measure the flow rate of liquid, gas and steam, especially suitable for low flow rate and small flow rate measurement.
Over the years, the metal tube float flowmeter with its excellent performance and reliability, as well as better performance price, in petrochemical, steel, electric power, gold, light industry, food, pharmaceutical, water treatment and other industries have been widely used.
Measurement Principle
HFM400 series of metal tube float flowmeter is mainly composed of two parts: sensor and indicator.The sensor is mainly composed of connecting flange, measuring cone, float and upper and lower guide.The indicator is mainly composed of housing, magnetic drive system, dial and electric remote transmission system.
In a vertical tapered measuring tube, there is a measuring component that can move up and down -- the float (FIG. 1). When the fluid moves upward through the tapered tube from bottom to top, the float is moved upward along the tapered tube by the force of the fluid.When the flow rate of the fluid increases, the displacement of the float increases.On the contrary, the displacement of the float decreases when the flow rate of the float decreases.In other words, the fluid flow determines the position of the float in the measuring tube, thus determining the size of the annular area between the float and the conical tube.When the flow rate of the fluid is maintained at a constant flow rate Q, the float is also in a state of dynamic equilibrium, staying at a position H in the conical tube. At this time, the annular area between the float and the conical tube remains constant.The float is acted upon by three forces: gravity G of the float, buoyancy F of the float, and fluid force P of the float. These forces are in equilibrium.According to Bernoulli force equation, force balance principle and fluid continuity law of fluid dynamics, the instantaneous fluid flow through the annular area can be calculated. Therefore, the metal tube float flowmeter adopts the principle of variable area to measure the flow.
Inside the float, a high performance permanent magnet is embedded to form a uniform and stable magnetic field around the float when the float is in a balanced position.A magnetic sensor is mounted on the outside of the conical tube so that the linear displacement of the float in the measuring tube can be transmitted in a non-contact form to the indicator, which, after detection and processing, is finally displayed on the indicator dial or output the corresponding standard 4 ~ 20mA current signal.
Features:
·It is suitable for measuring the flow rate of medium with small diameter and low velocity
·Reliable operation, small amount of maintenance, long life
·Requirements for straight section are not high
· Wider range ratio of 10:1
· Double-line LIQUID crystal display, field instantaneous/cumulative flow display
·There is a keyboard on the indicator for easy operation and setting
· All-metal structure, suitable for high temperature, high pressure and strong corrosive medium
· Non-contact magnetic coupling transmission
· Can be used in inflammable and explosive dangerous occasions
· Optional DC power supply or battery power supply mode
· With data recovery, data backup and power down protection functions
· Multi-parameter calibration function
