VALCOM ASL Series Ultrasonic Level Switch

VALCOM ASL Series Ultrasonic Level Switch

The VALCOM ASL Series Ultrasonic Level Switch is an advanced and highly versatile instrument designed to meet the demanding needs of both marine and on-land applications. With its exceptional liquid detection capabilities, pump control functionality, water ingress alarm systems, and overfilling protection features, the ASL Series offers a comprehensive solution for various industries. At the heart of the ASL Series is Valcom’s proprietary principle of distributed acoustic waves in a metal rod. This cutting-edge technology ensures accurate and reliable liquid level detection. By emitting acoustic waves into the environment, the instrument can determine if the rod is covered by liquid or not. When the liquid does not cover the rod, the acoustic waves disperse freely without any interference. However, as soon as the rod is submerged in the liquid, the emission of acoustic waves is muffled, leading to detectable interference. The integrated piezoelectric sensor promptly picks up this interference and converts it into a precise on-off signal, providing accurate feedback on the liquid level.

One of the key advantages of the ASL Series is its exceptional reliability, achieved through its static design. Unlike traditional level switches, the ASL Series has no moving parts, eliminating the risk of mechanical failure and reducing maintenance requirements. Additionally, the instrument operates without vibrations, ensuring stable and consistent performance even in harsh and dynamic environments. With its pure static technology, the ASL Series offers the highest level of reliability, contributing to enhanced operational efficiency and cost-effectiveness.

The VALCOM ASL Series Ultrasonic Level Switch is an exceptional instrument with a wide range of applications in the marine industry. Built for durability and precision, it provides accurate liquid detection and offers vital functionalities such as pump control, water ingress alarm systems, and overfilling protection. Whether on a marine vessel or in on-land installations, the ASL Series ensures reliable performance in challenging environments. 

The ASL Series operates on Valcom’s proprietary principle of distributed acoustic waves in a metal rod. This innovative technology guarantees accurate liquid level detection. When the rod is not covered by the liquid, the acoustic waves generated by the instrument disperse freely without any interference. However, as soon as the liquid covers the rod, the emission of acoustic waves is muffled, and this interference is detected by the integrated piezoelectric sensor. The sensor swiftly converts the detected interference into an on-off signal, providing accurate feedback about the liquid level. This precise functionality is particularly crucial for marine applications where maintaining appropriate liquid levels is essential for vessel stability and safety.

The ASL Series comes equipped with various specifications tailored to meet diverse marine requirements. It operates within a supply range of 12 to 30 Vdc, making it compatible with common power systems found on marine vessels. The current output is an ON-OFF signal with two options: 5 mA or 13 mA, providing flexibility in system integration. The frequency output is also adjustable, with two options of 1.2 kHz or 3.8 kHz, each with a ±30% tolerance. For enhanced control and automation, the ASL Series features relay outputs with a capacity of 1 A at 30 Vdc and a maximum switching power of 30 W or 2.5 VA. This allows seamless integration with pump control systems and other monitoring devices. The ASL Series offers excellent repeatability, with vertical mounting providing accuracy within 3 mm and horizontal mounting within 1 mm.

To ensure the ASL Series operates optimally in marine environments, it is designed to withstand extreme temperatures. The instrument can endure ambient temperatures ranging from -40°C to +85°C, making it suitable for various marine settings. Additionally, the ASL Series is available with finned bodies capable of withstanding even more extreme temperatures, ranging from -60°C to +150°C or -200°C to +450°C, depending on the chosen configuration. The ASL Series prioritizes safety and complies with various industry standards. It holds certifications and approvals such as ATEX, IECEx, Directive 2014/34/EU (ATEX), Directive 2014/68/EU (PED), Directive 2014/30/EU (EMC), and Marine Type Approvals from DNV GL and RINA. These certifications guarantee that the instrument meets stringent safety, performance, and environmental requirements, making it suitable for marine applications where regulatory compliance is essential.

In conclusion, the VALCOM ASL Series Ultrasonic Level Switch is a reliable and versatile instrument tailored for marine and on-land applications. With its advanced technology, static design, and exceptional reliability, it offers precise liquid detection, pump control, and overfilling protection. The ASL Series ensures accurate monitoring in marine environments, enhancing safety and operational efficiency for a wide range of marine vessels and installations.
