Description
The SPR-621 is a portable, non-contact ultrasonic flowmeter designed for measuring the flow rate and velocity of liquids in pipes. It uses advanced ultrasonic technology to provide accurate measurements without the need for pipe cutting or system shutdown. The device features a built-in data logger, rechargeable battery, and supports multiple installation methods for versatility across various applications.
Features
- Non-Contact Measurement: Measures flow without interrupting the liquid system
- Multiple Installation Methods: Supports V-method, Z-method, W-method, and N-method installations
- Built-In Data Logger: Stores up to 2000 lines of measurement data with time stamps
- Rechargeable Battery: Long-lasting internal battery for extended field use
- Wide Range of Liquid Compatibility: Works with standard and non-standard liquids (with sound speed input)
- User-Friendly Interface: Large LCD display with menu navigation and real-time diagnostics
- Communication Capabilities: RS-232 interface for data transfer and remote monitoring
- Automatic Signal Optimization: Displays signal strength and quality indicators for optimal transducer placement
- Time-Based Totalizers: Tracks positive, negative, and net flow totals with date/time stamping
- Password Protection: Prevents unauthorized changes to configuration settings
