Price Meters
Available in headphones or
digital styles, the Price Type AA meters offer fast, accurate
measurements for all but the lowest flows.
The headphone Model
generates one click every rotation or one every five rotations of the
shaft, according to the contact connection selected.
In the digital version, a
slotted hub extension rotates between a light-emitting diode and a
photo-receptor. The pulses produced when the slot aligns aligns with the
LED and phototransistor are routed to the digital flow indicator (Model
1100), which converts them to a direct digital readout of stream
velocity.
Either type can be suspended
from a bridge or boat using the suspension cable outfit with a lead
weight; or it can be mounted to on a wading rod for measurements in
shallow streams, ditches, conduits or wastewater systems.

Pygmy Meters
The compact design of pygmy
meters - the bucket wheel is just 3/4 inch by 2 inches in diameter -
allows measurement of shallower and lower velocity flows. The pygmy
meter provides reliable measurements of flows down to 0.05 feet per
second at depths as shallow as 3 inches. Except for the absence of a
five revolution click, these models operate identically to the larger
Price type meters in both headphone and digital models.
Pygmy meters are rod
suspended only.

* The
range of the pygmy meter can be extended to 11 fps with the 611 hand
counter (headphone model) and 15 fps with the Model 1100 flow indicator.
However, we recommend using the Price AA for velocities in this range.
