This product has been certified by the National Explosion-proof Product Quality Inspection Department according to GB3836.2000 "Electrical Equipment for Explosive Gas Environments Part 1: General Requirements", GB3836.2-2000 "Electrical Equipment for Explosive Gas Environments Part 2: Flameproof Type" d " "And GB3836.4-2000" Electrical Equipment for Explosive Gas Atmosphere Part 4: Intrinsically Safe "i" "passed the standard inspection. The explosion-proof marks are ExdⅡBT6 (flame-proof type) and ExiaⅡCT6 (intrinsically safe type). It is suitable for hazardous locations in Zones 1 and 2 of 0 (intrinsically safe type) containing explosive gas mixtures in the temperature groups T1 to T6 of IIA, IIB, and IIC.
This series of flow meters use advanced ultra-low-power single-chip microcomputer technology to develop a new type of intelligent flow meter integrated with turbine flow sensor and display integration. Through the micro processing unit, the signals collected by the temperature and pressure detection analog channels and flow sensor channels are collected. Compensate temperature and pressure according to the gaseous equation, and automatically correct the compression factor. All data (instantaneous flow, daily cumulative flow, total cumulative flow, temperature, pressure, time, date, battery power) are displayed on the LCD display, and Output working conditions, standard pulse signals, 4-20mA, RS485, IC card signals and other communication signals. The meter uses a built-in lithium battery and an external 24VDC dual power supply method. When the user does not need any signal output function, the meter does not need to supply power to the 24VDC. The meter automatically switches to the built-in lithium battery. The battery can work continuously for more than 3 years. This type of turbine flowmeter is an explosion-proof product with an explosion-proof grade: ExdIIBT6.
用户在选型时，应根据管道公称压力、介质较高压力、介质温度、介质组分情况、流量范围及信号输出要求合理选择流量计的型号规格。 Note: When selecting the type, the user should reasonably select the type and specifications of the flowmeter according to the nominal pressure of the pipeline, the higher pressure of the medium, the temperature of the medium, the composition of the medium, the flow range and the signal output requirements. In order to make the flowmeter have good performance, the flow rate range of the flowmeter should be more appropriate within the range of (20% ～ 80%) Qmax.
