FloWatch Air & Water Speed Flow Meter Kit (FW450) with Probes & Case

FloWatch FW450 is an accurate measurement device for water flow and air speed, as well as temperature measurements.

The Flowatch has been developed for use even in difficult conditions. Its various propellers offer measurement solutions in almost all cases, whether for measuring gas or liquid flows. An intrinsically-safe probe is also available for natural-gas measurements. Measuring range is from 2 to 93 mph (0.3 to 150 km/h).

• Instant speed measurements, wind or water.
• Speed units: km, h, m/s, knots, mph, fps and cm/s.
• Captures maximum & average speed, as as well as minimum and maximum temperatures.
• Selectable averaging period from 3 seconds to 24 hours.
• Backlit 4-line LCD with 0.4 inch (10mm) high digits.
• Completely waterproof and weatherproof.
• Battery indicator.
• Engineered in Switzerland.
• CE and RoHS approved.
• 1/4" base for tripod attachment.
• FLOW RATE:
  • Balanced impeller.
  • The impeller is magnetized, producing a magnetic field when rotating which is passed through the cable to the display unit.
  • Records maximum and average flow speed.
• TEMPERATURE:
  • Temperature adjusts quickly.
  • Temperature is read at the end of the rod.
  • Records maximum and minimum temperatures.
