Description

Providing 50% better accuracy than other HOBO Water Level Loggers (based on 0-13 feet range), this version is ideal for monitoring water levels and temperatures in wells, streams, lakes and wetlands.
 

Like other HOBO Water Level Loggers, the 13-foot version offers exceptional value and ease-of-use, with no cumbersome vent tubes or desiccants to maintain. This logger is ideal for recording water levels and temperatures in salt water environments.
 

IMPORTANT: The Hobo software and base unit need to be purchased with this logger. Please order via the recommended products area below.

 

Features

  • Lightning protection - no long signal wires, and electronics are shielded in stainless steel housing
  • HOBOware Pro software provides easy conversion to accurate water level reading, fully compensated for barometric pressure, temperature, and water density.
  • Multiple-rate sampling allows faster sampling at critical times such as when pumping starts or stops.
  • Available in 4 depth ranges
  • Ideal for use in wells, streams, lakes, wetlands and tidal areas
  • No-vent-tube design for easy reliable deployment
  • Available in stainless and titanium versions
  • Durable ceramic pressure sensor

Specifications

Pressure Sensor

  • Operation range: 0 to 145 kPa (0 to 21 psia);
    approximately 0 to 4 m (0 to 13 ft) of water depth at sea level,
    or 0 to 7 m (0 to 23 ft) of water at 3,000 m (10,000 ft) of altitude
  • Factory calibrated range: 69 to 145 kPa (10 to 21 psia), 0C to 40C
  • Burst pressure: 310 kPa (45 psia) or 18 m (60 ft) depth
  • Water level accuracy*:
    Typical error - 0.075% FS, 0.3 cm (0.01 ft) water
    Maximum error: - 0.15% FS, 0.6 cm (0.02 ft) water
  • Raw pressure accuracy**: 0.3% FS, 0.43 kPa (0.063 psi) maximum error
  • Resolution: < 0.014 kPa (0.002 psi), 0.14 cm (0.005 ft) water
  • Pressure response time: 90% < 1 second
  • Thermal response time (90%): Approximately 10 minutes in water to achieve full temperature compensation of the pressure sensor

 With accurate reference water level measurement and Barometric Compensation Assistant data
** Absolute pressure sensor accuracy includes all pressure drift, temperature, and hysteresis-induced errors
Maximum error due to rapid thermal changes is approximately 0.5%

Temperature Sensor

  • Operation range: -20° to 50°C
  • Accuracy: 0.37°C at 20°C
  • Resolution: 0.1°C at 20°C (10-bit)
  • Response time (90%): 3.5 minutes in water (typical)
  • Stability (drift): 0.1°C per year

Logger

  • Real-time clock: 1 minute per month 0 to 50C
  • Battery: 2/3 AA, 3.6 Volt Lithium, factory-replaceable
  • Battery life (typical use): 5 years with 1 minute or greater logging interval
  • Memory (non-volatile): 64K bytes memory (approx. 21,700 pressure and temperature samples)
  • Dimensions: 2.46 cm diameter, 15 cm length; mounting hole 6.3 mm diameter
  • Weight: Approximately 140 g
  • Wetted materials: Titanium, Viton o-rings, acetyl cap, ceramic sensor
  • Shock/drop :Logger is sensitive to shocks. Handle with care and avoid any impact. Always use proper packaging when shipping the logger.
  • Logging interval: Fixed-rate or multiple logging intervals, with up to 8 user-defined logging intervals and durations; logging intervals from 1 second to 18 hours. Refer to HOBOware software manual.
  • Launch modes: Immediate start and delayed start
  • Offload modes: Offload while logging; stop and offload
  • Battery indication: Battery voltage can be viewed in status screen and optionally logged in datafile. Low battery indication in datafile.

Applications

Include:

  • Sea Level Monitoring
  • Climate studies
  • Ocean ecology
  • Storm water impact
  • Wetlands restoration
  • Environmental impact
