The standard variable area flowmeter is composed of a measuring tube and a on-site indicator. On-site indicator can be optional to install an additional electric component, which is suitable to measure liquid and gas.
This variable area flowmeter adopts the variable-area measuring principle and the measuring component is composed of a conical measuring tube and a floater. The floater can move up and down freely in the conical measuring tube, to change the flow area in the tube. The vertical position of the floater in the conical measuring tube will change with the change of flow, the floater position will be transmitted to the indicator dial via magnetic transmission system, and it can indicate the flow value on site, and also output signal to realize remote display and control.

This variable area flowmeter can be widely used in the flow measuring process of complicated and severe environmental conditions such as petroleum, chemical engineering, power generation, pharmaceuticals, food and water treatment industries, as well as various medium conditions.

RS30C Rotor Spinning Machine-A new generation of semi-automatic spinning machines with fine quality, high efficiency and wide adaptability of raw material

a  The new generation of Spinning Machine improves the quality of the obtained yarn and the adaptability of its raw material is wide.

1  The design of fiber channel is optimized to achieve better evenness and higher strength for the obtained yarn with less defects; especially when the spinning the non-cotton fiber the friction coefficient of which is big, the fiber transfers smoothly and the quality of the obtained yarn is improved;

2  The new carding and inclusions removing system can adapt to worse raw materials to reduce the production cost.

b  The YOUYI jointing system with excellent jointing quality and ease of operation

1  The pneumatic controlled semi-automatic jointing system can automatically lift the bobbin in case of yarn breakage;

2  In the process of jointing, the doffing roller is depressed under the force of cylinder pressure and the yarn cone is put down to ensure the consistency of the jointing operation;

3  The concept of automatic jointing is introduced and the stepper motor is applied to control the feeding, thus the jointing quality is improved;

4  When the preparation work for jointing is done, the specially designed yarn breakage sensor would sense the feeding of yarn and automatically start the jointing. C

c  Lower production cost, higher productivity

1  Max can up to 480 rotors per machine;

2  When the speed of the rotor reaches 105,000 rpm, the servo would drive the traverse yarn guiding and the yarn guiding speed reaches200m/min;

3  The whole machine is driven via variable frequency and both sides transmit independently to reduce the assistant production time;

4  Low operating height and can be equipped with cans up to1200mmhigh.
