The Teledyne 2150EX Flow Module is an intrinsically safe Area Velocity meter specifically designed and Baseefa-approved for use in Zone 0 and Zone 1 potentially explosive atmospheres under ATEX Directive 94/9/EC. The smart digital probe ensures accurate measurements with long-term stability and reduced recalibration needs.
Features
- Rugged, submersible enclosure permanently sealed to meet IP68 (NEMA 4X, 6P) requirements
- Easy software upgrade via PC connection without affecting stored data
- Chemically resistant epoxy-encapsulated sensor
- Rollover memory with variable rate data storage
- Pressure transducer venting system for automatic atmospheric pressure compensation
- Quick connect Area Velocity sensor, easily removed and interchanged without recalibration
- High-capacity internal desiccant cartridge to prevent moisture
- Replaceable hydrophobic filter to protect against water intrusion
- Sealed AV sensor resists fouling by oil and grease
- 38.4k baud communication for fast setup and data retrieval
Applications
- Open channel flow measurement in hazardous locations (ATEX Category 1G)
- Portable and permanent-site AV flow monitoring for inflow, infiltration, sewer overflow, and other sewer studies
- Measuring shallow flows in small pipes; low-profile sensor minimizes flow obstruction and senses velocity in flows down to 25 mm depth
- Level measurement in explosive or potentially explosive areas, such as manholes, digesters, and storage tanks
Benefits
- Provides highly accurate, intrinsically safe flow and level measurements in hazardous environments
- Built-in calibration eliminates temperature drift, reducing recalibration frequency
- Powered by two lithium or rechargeable lead acid battery packs, or via network interface module
- Battery life up to 8 months with two-minute data storage interval
- Durable, chemically resistant design ensures reliability in harsh conditions
- Quick installation and easy sensor replacement minimize downtime
