Metal tube rotor flowmeter is a type of float flowmeter. Currently, many customers are gradually replacing glass rotor flowmeter with metal tube rotor flowmeter, which has high accuracy, high pressure resistance, high temperature resistance, and longer service life. Changzhou Chengfeng Instrument's third-generation metal tube rotor flowmeter further improves the usability and advantages of metal tube float flowmeters. It has the following characteristics: a one-time molded integrated inner and outer conical tube, a sturdy and simple measuring tube, a rotatable float that is not easily blocked, and magnetic components that are not affected by geomagnetic fields. Low pressure loss design, modular, intelligent, card type indicator. The new ESK transmitter is synchronized with the international market! After introducing the product features, let's talk about several types of metal tube rotor flow meters:
1. Ordinary type: made of stainless steel material, with on-site pointer indication, widely used.
2. Remote transmission type: equipped with LCD display and 4-20mA signal output metal tube rotor flowmeter, which can connect the signal to other places in PCL system for remote monitoring.
3. Jacket insulation type: Metal tube float flowmeter. When liquid with a temperature higher than the ambient temperature flows through the instrument in the pipeline, the temperature drops due to the increase of the heat dissipation surface, which can cause solidification or crystallization and cause poor float movement; When the viscosity of the fluid significantly changes due to a decrease in temperature and affects the measured value, a jacket insulation type should be selected. Sometimes, in order to prevent the fluid from absorbing heat from the outside, the jacket is also evacuated to achieve insulation effect.
4. Explosion proof type: The electric remote transmission float flowmeter of the metal tube float flowmeter is used when there are explosive gases or dust, and explosion-proof instruments should be selected. There are two types of explosion-proof design structures in China: explosion-proof design structures and intrinsic safety explosion-proof design structures. This explosion-proof is mainly implemented in remote metal tube rotor flow meters
5. Corrosion resistant type: The metal tube float flow can be divided into several materials, such as 304, 316L, stainless steel lined with PTFE. The corrosion resistant metal tube float flowmeter adopts F4 parts and F40 F46 plastic lined metal parts structural design.
