The HS-2000 intelligent external ultrasonic liquid level meter (hereinafter referred to as “liquid level meter” or “meter”) can measure liquid levels outside a tank consistently and without the need for drilled holes. This allows for quick, simple installation that does not interrupt the tank’s operation or replacement for updated meters. The meter can also acquire accurate liquid level measurements for high-pressure hermetical tanks containing toxic, highly acidic or alkaline, and other various types of pure liquids. It is designed to be explosion proof, allowing the product to be used in a variety of additional applications with anti-explosion requirements.
Advantages
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.
Self-Calibration
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.
Self-Test
The liquid level meter can self-test its own operating status and hardware conditions, ensuring reliability and stability.
One-Key Recovery
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.
Application Requirement
1 Medium Purity Degree
Liquids should not contain dense foam
There should be minimal suspended objects in the liquid, such as crystallized particles, etc.
There should be minimal precipitation in the tank, such as mud, sand, etc.
2、Tank Material:carbon steel, stainless steel, various hard metals, glass fiber-reinforced plastics, epikote, rigid plastics, ceramics, glass, ebonite, other composite materials.
3、Tank Shape:Spherical, horizontal and vertical tanks are permitted.
The HS-2000 external ultrasonic liquid level meter utilizes ultrasonic echo measuring principles and a high-speed signal processing chip. Its signal penetrates the wall of the tank and achieves non-contact and accurate measurement of liquid levels 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.
