2031H Series Electronic Flowmeter
Weight in Air: 225 grams (8 ounces).
Weight in Water: 113 grams (4 ounces)
Materials: Celcon rotor. Nickel-plated brass nose cone. Polycarbonate body. Armaloyed stainless steel main rotor and idler gear shafts.
Dimensions: 21.3 cm (8 3/8") overall length.
Standard rotor diameter: 6.98 cm (2 3/4").
Low-speed rotor diameter: 16.5 cm (6 1/2").
Depth Rating: Unlimited (free flooding).
Data Readout: Six 10-digit counter wheels reading 000000 to 999999. Ten counts per rotor revolution, non-resetting. Read by noting difference in beginning and end readings. (counter advances through 000000).
