Global Water produces a line of instruments for measuring the flow of water, from 2" pipes to rivers. They feature digital computer readouts and can be calibrated for the type of water flow they are measuring. The world-wide standard for measuring the velocity of water for over 12 years.
Global Water Adjustable Turbine Flow Meter
The TX100/200 series, adjustable insertion turbine flow sensors, use ruby bearings and a non-drag pick-off to achieve a wide flow range and long life. A sensor detects the passage of miniature magnets in the rotor blades (magnets are in 2 or 4 blades only). The resulting square-wave signal can be sent for hundreds of feet without a transmitter, over unshielded cable. This square-wave signal can be sent directly to a PLC or other control, or can be converted using a blind 4-20mA output or flow rate and totalizer display.
Global Water Flow Probe
This digital water velocity meter consists of a turbo prop sensor attached to an expandable handle with a digital readout display. Incorporates true velocity averaging for accurate flow measurements. Used for measuring flows in rivers and streams and monitoring the velocity in ditches and canals.
