Mechanical Flow Meter
• Will work with plankton nets.
• For horizontal tows or in moving water
• Does not block sample! An accurate, convenient way
to measure flow in streams, rivers or with plankton nets.
Balanced to maintain a horizontal position when suspended
from a tow line. This simple, reliable instrument features
a nickel-plated brass nose cone, clear polycarbonate body
and precision molded rotor connected to a six digit
counter which displays each revolution on an odometer.
Unlimited depth capacity. Includes: 8-3/8” long flow
meter, 18” stainless steel tow line and stainless steel
connecting axle pin. Optional telescoping aluminum rod
extends to 8’ to measure currents from river banks and
bridges for stream sampling. |

Model
2030 series
Mechanical Flowmeters
The model 2030 series Digital, Mechanical Flowmeter is a compact,
general purpose instrument for flow measurements in rivers, estuaries,
canals, sewage outfalls, and offshore applications. It is ideal for
determining water speed, volume, or distance.
The Flowmeter incorporates a precision molded rotor coupled directly to
a six digit counter which registers each revolution of the rotor and
displays it in a fashion similar to that of an odometer. The counter is
located within the body of the instrument and is displayed through the
clear plastic housing.
- Ballasted for dynamic in situ
stability
- Unlimited depth capability

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).
