Gas Turbine Flowmeter turbine flowmeter 4-20mA output ammonia flow meter gas turbine flowmeter

Features

l High measurement accuracy, good repeatability, wide range ratio, up to 1:20 (or wider);

l The use of pure imported bearings and instant oil injection system, the flowmeter has small friction resistance, good sealing performance and long service life;

l The carefully designed reverse thrust structure and unique structure ensure the reliability of long-term bearing operation;

l Embedded protection circuit such as lightning protection, anti-surge, pulse group suppression, etc., the external transmission interface is electrically isolated, and the anti-interference is strong and reliable;

l High-precision digital temperature sensor and digital pressure sensor are adopted, and the digital pressure sensor has its own temperature correction function, high pressure detection accuracy, long-term stability and low temperature drift;

l Anti-strong magnetic interference, can prevent theft;

l Intelligent integrated design, which can dynamically detect the temperature and pressure of the medium, and perform automatic compensation and compression factor correction to directly display the temperature, pressure, instantaneous working condition volume, instantaneous standard condition volume, and working condition cumulative volume and standard cumulative volume. ,battery capacity;

l Advanced dual-supply micro-power high-tech, low power consumption of the whole machine, can not only work stably with long-term internal battery (Lithium battery can be used for 5 years), but also can be connected to external power supply;

l Large-screen backlit LCD display (only when externally powered) for clear and intuitive reading in darker environments;

l The meter can output a pulse signal or output a 4-20mA standard analog signal according to the user's needs;

l It can output IC card quantitative pulse signal and use it with IC card controller;

l Adopt RS485 interface MODBUS protocol: It can be combined with dedicated MODEM to build automatic meter reading management system through network, with high degree of automation;

l Using EEPROM data storage technology, the parameter can be stored for a long time after power off. Important data double backup calculation, important data is stored in two memories at the same time to ensure data security;

l The internal battery low battery automatic alarm (≤ 3.2V), reminding the user to replace the battery in time;

l Accidental power failure automatically saves data to prevent data loss;

l The external circuit is isolated from the main circuit and the isolation voltage is up to 1000V；

l The instrument has an explosion-proof function, the explosion-proof mark ExiaIICT4 (intrinsically safe type); the flowmeter case protection class is IP65.
