DESIGN & BENEFIT

² Patent rectification technology can maintain the measurement reliability under unfavorable installation condition and relatively significant change of medium speed flow condition.

² Unique dust-proof structure can effectively prevent impurities in the medium from entering into bearing and resulting in rapid wearing and deadlock.

² Minimum installation requirement, in which the front straight pipe section ≥ 2D can ensure measurement accuracy of the flowmeter.

² Aluminum alloy turbine is characterized in high strength, corrosion resistant, ageing resistant, long service life, high accuracy and well repeatability.

² Advanced microcomputer technology and mono-chip computers with high performance enable the complete machine to have more powerful function and more excellent performance.

² Advanced Hi-tech double power supply and micro power consumption enables the complete machine of low power consumption and to be either supplied with internal batteries and run for a long time (two lithium batteries can be used for 3 years) or connected to external power to run.

² Large screen back-lighting LCD display can be read clearly and visually in darker environment.

² Infrared remote operator may be matched and parameter setting can be carried out without opening the front cover of flowmeter.

² The flowmeter is provided with pulse signal output and may also output many signals according to user’s need such as 4 to 20 mA standard analog signals and quantization pulse signals of IC card etc.

² Adopt RS485, RS232C, MODBUS, HART protocols: they can be matched with specific MODEM and construct automatic meter reading management system through telephone network, leading to a high automation level.

² Low voltage alarm of internal battery (≤2.7V) can remain the user to replace the battery in time.

² The intelligent flow totalizer can be turned 180° for convenient reading.

² Data can be saved automatically when there is power failure to prevent data loss.

² Signal output check function is provided. It can output the standard current signals of 4, 8, 12, 16 and 20 mA.

² Liquid crystal display screen of totalizer can withstand high temperature of 80℃.

² Reliable electromagnetic compatibility design.
