- Superior Probe Design Provides long term level stability, no temperature drift, no span calibration required and is field interchangeable
Overview
This product is discontinued for purchase, but still available for hire. If you wish to purchase an ATEX Flow meter the Laserflow EX
is available to purchase.The 2150EX ATEX-rated Area Velocity Flow Meter is built on digital electronics, so the analog level is digitized in the sensor itself. The probe is factory calibrated for a 3 meter span at different temperatures. This calibration eliminates drift in the level signal and provides long term level stability. This reduces recalibration frequency and completely eliminates span recalibration.
The 2150EX flow meter is powered by two lithium or rechargeable lead acid battery packs, or by the 2194EX network interface module. The battery has a life of up to 8 months at 2 minute data storage intervals due to highly efficient power management.
Standard Features of the 2150EX
- Rollover memory with variable rate data storage, lets you change the data storage interval when programmed conditions occur.
- Sealed AV sensor resists fouling by oil and grease, eliminating frequent cleanings needed with electromagnetic probes.
- Pressure transducer venting system automatically compensates for changes in atmospheric pressure to maintain accuracy
- Rugged, submersible enclosure is permanently sealed to meet IP68 (NEMA 4X, 6P) requirements
- High-capacity internal desiccant cartridge keeps the vent free of moisture during normal operation
- The unit is easy to upgrade. New operating software can be downloaded into non-volatile "flash" memory via PC connection, without affecting stored program and data, and without removing the 2150EX from the hazardous area.
- Chemically resistant. The epoxy-encapsulated sensor withstands tough applications.
- Quick connect area velocity sensor can be easily removed and interchanged in the field with no recalibration.
- Replaceable hydrophobic filter protects against intrusion of water during submersion.
- Sealed AV sensor resists fouling by oil and grease, eliminating frequent cleanings needed with electromagnetic probes.
- 38.4k baud communication provides speedy setup and data retrieval.
