Product Overview     

GML601-A general-purpose ultrasonic material (liquid) position meter is a Powerful ultrasonic level transmitter, which has taken advantage of many kinds of level instruments at home and abroad. The universal level meter with full digital and humanized design concept has perfect level measurement and control, data transmission and human-computer communication. This product adopts modular circuit design, military quality multi-layer PCB board, compact hardware structure, and reasonable layout. This product supports isolated 4-20mA output, built-in GPRS, RF, LORA, Bluetooth, Wifi to achieve wireless data transmission such as the Internet of Things, support MiniSD card data acquisition or USB storage, can also add modules to achieve other functions according to customer needs.

GML601-A uses imported industrial-grade chips, digital temperature compensation, etc… related ASICs. It has a strong anti-interference ability, can set arbitrarily upper and lower limit nodes and online output adjustment, and has an on-site display. The outer casing is made of engineering plastic ABS waterproof casing, and the casing is compact and quite sturdy. This product can meet most liquid level and material level measurement requirements without touching industrial media, and completely solves the shortcomings such as winding, clogging, leakage, medium corrosion and inconvenience caused by traditional measurement methods such as pressure type, capacitance type, and float type. Therefore, it can be widely used in various fields related to material level and liquid level measurement and control. This product has been tested and approved by the national authority. This product meets the requirements of GB3836.1-2010 and GB3836.4-20010 national standards. The explosion-proof mark is ExiaIIBT4Gb.
