OHSAS 18001 GE 1202 ISO9001 ISO14001 Ultrasonic Level Meter USER MANUAL A YITE INSTRUMENT CORP http www ayite net GE 1202 Ultrasonic Level Meter AYITE TECHNOLOGY http www ayite net 1 Overview Sincerely thank you for buying our ultrasonic level meter The GE 1202 meter includes several proprietary technologies is safe and clean with high precision and long service life stable and reliable and convenient to install and maintain and is applicable to various fields of acid alkali salt anticorrosion and high temperature The meter is with following features For circuit design high quality power modules are selected to be as power supply parts and highly stable and reliably imported devices are used as components of the meter It can fully replace imported foreign meters of the same type Patent sonic wave intelligent technology software can make intelligentized echo analysis It needs neither debugging nor other special steps This technology has functions of dynamic thinking and dynamic analysis Our sonic wave intelligent patent technology greatly improves the meter s precision and the precision of liquid level is up to 0 2596 which is enough to resist various interference waves The meter is a non contact one and does not directly contact liquid so the fault rate is low The meter can be installed in several different ways and the user can make meter calibration according to the Manua2. Explosion proof is avallable too
3. f the transducer launching surface to the highest level is less than the blind area of the purchase instrument is required to install an extension tube that diameter is greater than 200mm and the length is 0 35m 0 50m 3 6 Installation Notes 1 The instrument used outdoors it is best to install awning or the protecting housing so as to avoid the LCD screen ageing affected by sunlight 2 Wire cable protection pipes pay attention to sealing to prevent water and prevent mice and other rodents Bite 3 Although the instrument itself with a lightning protection device but the instrument when used in a multi mine area it is recommended into the outlet end of the instrument to install lightning protection devices dedicated 4 Instruments are used in particularly hot cold places which mean there is likely to exceed the ambient temperature around the instrument s work requirements so we propose increase fortify high and low temperature devices around the liquid level gauge 4 Debugging of meter 4 1 Keyboard directive COM CS 2 SET Press SET about 3 second It will appear 0000 the first 0 is flashing change the first O as 1 then Press OK button enter the parameter setting menu After Finish setting then press SET key to exit the parameter setting menu Al Page up key and number key In menu the key is used as the page up key of menu when changing data the key is used as number key to add number V Page down key In me
