High temperature (optional) H1 medium temperature: 120 ° C - 160 ° C H2 medium temperature: 160 ° C - 250 ° C H3 medium temperature: 250 ° C - 400 ° C LZDC series metal tube ( Also known as metal rotameter) it has a simple structure, reliable operation, wide application range, high precision, easy installation and so on. Compared with the series flow meter glass rotor flowmeter, with high pressure, high temperature, strong sense of security, simple reading and so on. Suitable for flow measurement and opaque media and corrosive media. Meter tube and flange made of stainless steel (ICr18Ni9Ti or OCr18Ni12Mo2Ti). Float made of stainless steel, corrosion-type float and tube lined with Teflon PTFE. The measuring principle shown in Figure 1, the flow sensor and flow indicators of two parts. Float vertically mounted in the conical measuring tube, due to the action of the fluid it can float freely up and down in the conical tube. The float inside the permanent magnet is embedded with a high performance, along with the float fluctuate magnets in magnetic field generated around also changed. When the flow stabilized at balancing the float, the magnetic field surrounding the distribution has reached fixed. By measuring tube and the tapered flow indicator mechanical connection, can float in the form of a non-magnetic signals passed out of the contact, that is to say, the indicator may be the value of the flow rate of fluid delivered by way of a magnetic detection and treatment, the final The size of the flow is directed through the pointer indicates the indicator dial, while LCD readout also instantaneous and cumulative flow value, standard two-wire output (4-20) mA signal / HART protocol.
