Description
Advancing Level and Flow Measurement with Radar
In the complex landscape of industrial measurement, the need for accurate and versatile instrumentation is paramount. Traditional sensors often fall short when dealing with highly corrosive chemicals, or when a single device is required to perform multiple functions, such as both level and flow measurement. The OPTIWAVE 1540, a state-of-the-art 80 GHz radar level transmitter, is engineered to meet these challenges head-on. This device offers a cost-effective, non-contact solution for a wide range of applications, including liquid chemicals and open-channel flow. It operates by emitting a highly focused radar beam and measuring the time it takes for the signal to reflect off the surface of the medium. This non-intrusive method ensures exceptional accuracy and reliability without any moving parts, making it an ideal choice for a diverse set of demanding environments.
A Compact and Robust Chemical-Resistant Design
The OPTIWAVE 1540 is built to withstand the rigors of chemical processing. Its compact and robust housing, along with its flush-mounted PVDF Lens antenna, provides superior resistance to a wide range of corrosive liquid chemicals. The PVDF material is a key advantage, as it does not degrade under exposure to harsh media, ensuring the sensor’s long-term integrity and accuracy. This design also allows for reliable level measurement in pressurized tanks at moderate pressures of up to 5 bar (72.5 psi). For added durability, the OPTIWAVE 1540 is also available in an IP68-rated waterproof version, which offers a crucial layer of protection in environments exposed to heavy rainfall or potential flooding, such as outdoor chemical storage areas or wastewater applications.
Precision and Agility with 80 GHz Radar
The use of 80 GHz radar technology is a cornerstone of the OPTIWAVE 1540’s performance. This high-frequency signal allows for a small beam angle of just 8°, which is critical for reliable level measurement in narrow tanks, channels, or vessels with internal obstructions. A narrow beam minimizes the risk of the radar signal reflecting off tank walls, ensuring the measurement is of the actual liquid level. Furthermore, the OPTIWAVE 1540 boasts an extremely high dynamic range, enabling it to deliver reliable readings even in the presence of challenging conditions like condensation or agitated surfaces. The sensor also features dedicated algorithms to filter out and compensate for these interferences, guaranteeing a consistently accurate and stable measurement.
Dedicated Applications in Diverse Industries
The versatility of the OPTIWAVE 1540 allows it to serve a wide range of specific applications. In the chemical industry, it is ideal for level measurement in IBCs (Intermediate Bulk Containers) and chemical storage tanks. Its ability to measure through the roofs of closed tanks made of non-conductive materials eliminates the need for direct installation, a significant safety and convenience benefit. In the water and wastewater sector, the OPTIWAVE 1540 can be used as a cost-effective flow transmitter in open channels, such as canals and rivers. By measuring the level of the liquid and using the geometry of a Venturi section, the device can accurately determine the flow rate, a crucial function for environmental monitoring and flood warning systems. It is also an excellent choice for measuring the level of Combined Sewer Overflows (CSOs), where its robust design and accuracy are essential.
User-Friendly Commissioning with Bluetooth®
One of the standout features of the OPTIWAVE 1540 is its user-friendly commissioning process. The device utilizes Bluetooth® connectivity, which allows technicians to easily set up and configure the transmitter using the OPTICHECK Level Mobile app on a smartphone or tablet. This wireless approach is a major advantage, as it eliminates the need for complex, wired configurations and allows for quick and safe setup from a distance. The intuitive app guides the user through the setup process, making it possible for personnel without extensive technical knowledge to commission the device with ease. This streamlined process saves time, reduces the risk of errors, and enhances overall operational efficiency.
Intelligent Diagnostics and Continuous Verification
The OPTIWAVE 1540 is equipped with built-in OPTICHECK technology for enhanced device diagnostics. This intelligent feature enables continuous self-checking and verification of the device’s performance without any process interruption. The technology can generate a one-click verification report that provides a clear overview of the device’s status. This is an invaluable tool for ensuring compliance and maintaining operational efficiency. The transmitter is drift-free and maintenance-free, meaning there is no need for recalibration over time. Its robust design and advanced diagnostics reduce the total cost of ownership and ensure that the measurement data remains reliable for the life of the product. The system’s ability to provide on-site verification without removing the device from the process is a significant benefit, simplifying maintenance and improving safety.
