HS-2000 intelligent external ultrasonic liquid level meter (hereinafter referred to as“liquid level meter” or “meter”) can measure liquid level outside tank constantly without the need for drilled holes in the tank. This allows for quick, simple installation that does not interrupt the tank’s operation and replacement of updated previous meter. Additionally, the meter can acquire accurate liquid level measurements for high-pressure hermetical tanks containing toxic, highly acidic or alkaline, and various types of pure liquids. Its explosion proof feature as designed allows it to be used in the applications and conditions which require anti explosion.
HS-2000 external ultrasonic liquid level meter utilizes ultrasonic echo measuring principle and a high-speed signal processing chip. Its signal penetrates the wall of the tank and ultimately achieves completely non-contact and accurate measurement of liquid level in tanks. In addition, the liquid level meter can output a 4～20mA standard signal or transmit measurement results to a computer ( or secondary meter ) via an RS-485 interface.
Non-Contact Liquid Level Measurement
The ultrasonic sensor (probe) is designed to be installed on an external surface of a tank wall without the need to drill holes on the measured tank.
This function eliminates accuracy loss due to long term usage.
Infrared Debugging During Operation
This function is especially suitable for conditions where it is dangerous to open the meter cover to debug, making the debugging process simple.
The liquid level meter can self-test its own operating status and hardware conditions, ensuring reliability and stability.
If the liquid level meter is not functioning properly, the user can press the one-key recovery button on the remote control to allow the liquid level meter to return to normal working condition.
On-Site Display and Remote Transmitting
The liquid level meter can not only display data on site, but also transmit data to a control room located away from the site via signal wire.
