Fully portable, precalibrated and easily installed flow metering device capable of accurate
measurement in all sewer and storm water flow conditions.
- Greater accuracy -- with error factors as low as three percent of full scale (at open channel and
full pipe flow operating conditions), compared to ten percent and higher for velocity-area
flowmeters. This device offers greater performance accuracy than any other sewer flowmeter on
- No field calibration required -- the user can save valuable time because calibration
in the sewer is not required (the device is already precalibrated to meet National Institute of
Standards and Technology standards).
- Ease of installation -- installers can be in and out of the
sewer in less than ten minutes.
- Increased versatility -- this is the only flowmeter that accurately
operates under all flow conditions (partially filled or full pipe, reverse flow and submerged flow).
The device also provides accurate readings during the transition from partial to full pipe flow.
Examples of Applications and Markets:
The major market for the flowmeter is in municipalities for infiltration/inflow studies, capacity
studies and sewer flow monitoring. Typically, the flowmeter is placed in a sewer line to collect
data for several days or weeks and then moved to another location. Hence, ease of installation is
a very important consideration. Another small, but rapidly emerging market is the area of
monitoring industrial discharges into municipal sewer systems or waterways. The flowmeter has
also been used to measure water use efficiency by comparing wastewater effluent flows to water
use to determine process losses.
Selective field trials completed. This novel product, winner of the prestigious R&D 100 award,
was previously offered by TN Technologies Inc. as the DataGatorTM. U.S. Department of
Agriculture, Phase II developed larger sizes of flow tubes. Related technology -- completed U.S.
Advanced Research Project Agency, Phase I project for wireless communication between
manhole and field.
Patents for the flowmetering technology are available for license or outright sale. YES can
