The Prosonic Flow Clamp-On 91W by Endress+Hauser is an ultrasonic transit-time flowmeter designed for non-invasive, external measurement of water and wastewater systems. Ideal for applications in drinking water, process water, saltwater, deionized water, cooling, and heating circuits, it offers a cost-effective solution for flow monitoring without interrupting the process.

Key Features

• Non-Contact Measurement: Utilizes ultrasonic technology to measure flow from outside the pipe, eliminating the need for pipe penetration.
• Wide Pipe Compatibility: Suitable for pipe diameters ranging from DN 15 to DN 2000 (½" to 80").
• Temperature Range: Operates in medium temperatures from -20°C to +80°C (-4°F to +176°F).
• IP68 Protection: Ensures durability and reliability in various environmental conditions.
• Automatic Frequency Scan: Enhances measurement performance by automatically selecting the optimal frequency.
• Maintenance-Free Installation: Features a clamp-on design with corrosion-resistant materials, reducing maintenance needs.
• Heartbeat Technology: Provides continuous self-monitoring and diagnostics for proactive maintenance.
• Short Inlet Run Capability: Thanks to FlowDC technology, it allows installation in locations with short inlet runs.
• Web Server Interface: Enables remote configuration and monitoring via a web browser.
