Full digital processing, strong anti-interference ability and reliable measurement.
Ultra-low EMI switching power supply, suitable for power supply voltage variation range, high efficiency, small temperature rise; good EMC performance.
Chinese and English menu operation, easy to use, easy to operate, easy to learn and understand.
High definition backlight wide temperature LCD display.
It can perform bidirectional flow measurement and bidirectional total accumulation; it has automatic range switching function, which can effectively improve the measurement accuracy of analog current and frequency output, especially suitable for occasions where the diurnal flow range changes greatly and needs to send control signals; flow measurement range Up to 1500:1.
There are three totalizers inside, which record and display the forward cumulative amount, the reverse cumulative amount and the accumulated difference integrated amount, which are convenient for fluid metering and custody transfer.
Provide isolated or non-isolated RS485/RS232C digital communication interface, and support fieldbus communication modes such as MODBUS, PROFIBUS-DP and HART.
Constant current source fluid resistance measurement can accurately measure the internal resistance of the electrode signal in the case of long-line transmission. It can be used not only to determine whether the fluid in the sensor is empty or not, but also to identify abnormal phenomena such as contamination and coverage of the electrode, and to provide cleaning for the user. Fault processing information such as electrodes.
Turbine flow meter applications
Turbine flow meters are widely used in the following measurement objects: petroleum, organic liquids, inorganic liquids, liquefied gases, natural gas, gas and cryogenic fluids. In the transshipment and gathering stations of foreign liquefied petroleum gas, refined oil and light crude oil, the first and last stations of large crude oil transmission pipelines use it for trade settlement. In Europe and the United States, the turbine flowmeter is the natural gas meter next to the orifice flowmeter. In the Netherlands alone, more than 2,600 gas turbine flowmeters of various sizes and pressures from 0.8 MPa to 6.5 MPa are used on the natural gas pipeline. Has become an excellent natural gas flow meter. Although the excellent metering characteristics of the turbine flow meter are favored by people, the impression is that the moving parts are short in use time, and they are inevitable in the selection. After people's unremitting efforts, it should be said that the situation has changed a lot. As the most versatile flowmeter, the turbine flowmeter has been developed into a multi-variety, full-series, multi-size mass production scale.
Plug-in electromagnetic flowmeter features
Corrosion-resistant full stainless steel material, ABS full mold production probe structure is simple, firm, no moving parts, long service life, reliable measurement, strong anti-interference ability, small size, light weight, easy installation, small maintenance range, large measurement range, temperature-free measurement The influence of changes in density, pressure, viscosity, conductivity, etc., zero pressure loss can be installed and disassembled under continuous flow, which brings convenience to the user's maintenance. The manufacturing cost and installation cost are lower than the general electromagnetic flowmeter. It is especially suitable for large and medium-diameter pipeline flow measurement. It adopts advanced processing technology, solid-state packaging, vibration resistance and long life. It makes the meter have good measurement accuracy and stability. The flowmeter not only has 4-20mA current signal output, but also has 1-2000HZ frequency output digital communication output: RS485, RS232, HART, Modbus.
