Is set intelligent gas lobed rotor meter, the flow rate, temperature, pressure testing functions in one body, and the automatic temperature and pressure compensation to a new generation of flow meter, gas is a kind of compressible fluid, the volume value is closely related to the temperature and pressure, in order for unity to be trade both sides - standard, it is necessary to convert the actual volume to benchmark conditions of standard volume (101.325) KPa20C). To achieve this goal, the intelligent gas waist flowmeter can accurately correct the volume of the gas. It is an ideal instrument for gas measurement in petroleum, chemical, electric power, metallurgy and other industries.
■ High precision, temperature, pressure, flow sensor and intelligent volume correction in one, can detect the temperature, pressure and flow of the measured gas, and automatic flow tracking compensation and compression factor
■ Adopt advanced microcomputer technology and high performance integrated chip, the whole machine has powerful function and superior performance.
■ The circuit adopts surface mounting technology, compact structure, strong anti-interference ability, high reliability.
■ Pressure sensor, temperature sensor, flow sensor are all built in, making the structure more compact.
■ Advanced micro power consumption technology, low power consumption of the whole machine, that is, by the built-in battery long-term power supply operation, but also by external power supply operation.
■ According to the flow frequency signal, the instrument coefficient can be segmented automatically linear correction, so as to improve the accuracy of the instrument.
■ With fault self-diagnosis and alarm function, high reliability, LCD display, clear and intuitive, convenient reading.
■ The flowmeter has pulse signal output, or 4~ 20mA standard analog signal output according to user needs.
■ The meter has its own real-time database, through the RS-485 communication interface and the factory's special MODEM matching, can form a telephone meter reading network, convenient data collection and real-time management.
■ Advanced micro power consumption technology, low power consumption, using built-in battery can run for more than five years.
■ Local display of flow value, and with a variety of signal output functions to meet the needs of different sites and systems.
■ Use E2PROM data storage chip to save user parameters, manufacturer parameters and certain historical records.
■ High contrast three line LCD display, can display date, standard cumulative flow, standard instantaneous flow, medium temperature, pressure value and battery voltage.
■ With real-time data storage function, can prevent battery replacement or sudden power failure of data loss, in the state of power failure, internal parameters can be permanently saved.
