Beijing North Branch letter supply Vortex Flowmeter

LUGB type vortex flowmeter is to measure the volumetric flow meter of gas, vapor or liquid volume flow, standard condition volume flow or mass flow according to Carmen (Karman) vortex principle. And it can be applied as a flow transmitter automation and control systems. The instrument uses advanced differential technology, with isolation, shielding and filtering measures to overcome the shock of similar products is poor, small-signal data disorders and other issues, and uses a unique sensor packaging technology and protective measures to ensure product reliability . Basic and complex products are of two types, the basic type measuring single flow signal; complex enabling simultaneous measurement of temperature, pressure, flow rate. Each type has a whole sub-structure to accommodate different installation environments. Two instrument characteristics and use characteristics: 1. no moving parts, long-term stability, simple structure, easy to install and maintain 2. Using interference cancellation circuit and vibration sensor head, a certain resistance to environmental vibration performance 3. With ultra-low power single-chip microprocessor technology Section 1 3.2V10AH lithium batteries can be used more than 5 years The software on the instrument coefficient nonlinear correction, to improve measurement accuracy 5. The pressure loss, wide measuring range 6. cumulative flow using EEPROM power-down protection, protection longer than 10 years Uses: The instrument can be widely used in large, medium and small variety of pipes for drainage, industrial recycling, waste water treatment, oil and chemical agents as well as compressed air, saturated and superheated steam, gas and a variety of medium dosing flow.
