Before purchasing the KATflow 200, it had to interrupt the process and introduce an orifice meter or V-notch weir
and mechanical flowmeter to measure flow.
To carry out dam safety analysis based on relationships between reservoir-specific seepage and reservoir water levels, the seepage flow measured at a V-notch weir of the downstream toe is adjusted to filter out rainfall-induced infiltration into the downstream shell.
It consists of a V-notch weir and an ultrasonic-type sensor to measure the overflow height.
The monitoring constructed wetland consisted of some instruments installed at the inlet and outlet including two rain gauges, V-notch weir with pressure sensor probe for flow measurement, data logger for recording rainfall and flow data, and spread spectrum Radio Frequency (RF) modem and Global System for Mobile communication (GSM) modem to support telemetry system.
In order to obtain a good comparison during the calibration process, a noise suppression technique was required to reduce the data noise due to the sensitivity of the pressure sensor reading the fluctuating water depth in the V-notch weir boxes.
The re-coating of the circular primary and secondary clarifier metal work includes the steel V-notch weir
plate, steel scum baffle, steel rake arm, steel skimmer arm, steel scum trough, steel center baffle, steel center support structure and steel rake arm support.
They can be used in reservoirs and drinking water storage, in rivers, boreholes, aquifers, environmental monitoring and for V-notch weir
The KUB pilot plant maintains constant flow by a sampling pump that provides excess flow to a V-notch weir
with a variable overflow.
* A variety of built-in flumes and weirs for determining flow rates including Parshall flumes, cut-throat flumes, California-pipe weirs, rectangular weirs and v-notch weirs
The backfill placed inside all drainage chambers located around the site should be excavated, the drainage systems and v-notch weirs
brought back into operation and the chambers protected from public access by suitable covers.
For accurate measurement of small flows, V-notch weirs
