In chemical storage tank areas, highly corrosive media and high-pressure environments often cause traditional level gauges to fail frequently. In food processing workshops, sanitary standards impose strict requirements on the cleaning costs of contact-type equipment. In oil storage tank farms, leakage risks from flammable and explosive media are always a constant concern. In response to these industry pain points, external-mount ultrasonic level sensors, with their core advantages of non-intrusiveness, high reliability and intelligence, are redefining the technical paradigm of level monitoring.
I. A "Liquid Level Perspective" That Penetrates Through Tank Walls
The technological breakthrough of Bevord external‑mount ultrasonic level sensors stems from the in‑depth utilization of ultrasonic propagation characteristics.
Its working principle can be broken down into four steps:
- The sensor, attached to the outer wall of the vessel, emits high‑frequency ultrasonic waves that penetrate the vessel wall and enter the medium.
- Reflected waves form at the interface between the medium and air (the liquid surface).
- The built‑in microprocessor captures the time difference between transmission and reception.
- Combined with the sonic velocity of the medium and vessel parameters, it accurately calculates the liquid level height through algorithms.
This process requires no drilling or contact with the medium,
completely eliminating the risks of corrosion, clogging and leakage associated with traditional contact level gauges.
II. A Cross-Industry Universal "Level Guardian"
The non-intrusive design of Bevord external‑mount sensors makes them a versatile solution for liquid level monitoring across multiple industries.
In the petroleum industry, gas stations achieve real‑time monitoring of oil tank levels with external‑mount sensors. The no‑drilling design minimizes risks of flammability and explosion to the lowest level. Meanwhile, it supports 4G remote transmission, allowing managers to view data anytime via a mobile APP.
Modern industry’s demand for liquid level monitoring has evolved from basic measurement to intelligent management.By integrating IoT technology, external‑mount sensors achieve a closed loop from data acquisition to decision support.It enables seamless connection to automation systems such as PLC and DCS.It supports the Modbus‑RTU protocol and works with host computer software to implement functions including liquid level alarm and trend analysis.Wireless modules are optional, allowing data to be uploaded to the cloud via 4G / NB‑IoT to build a remote monitoring platform.A pharmaceutical enterprise used this function to centrally manage liquid level data from 20 storage tanks scattered across the plant.With AI algorithms predicting liquid replenishment time, it reduced raw material waste by 15%.
