CNFMS Objective
• CNFMS is a web based software application for Canal Network Flow Monitoring System as part of ClimaAdapt to monitor canal flow (static and dynamic) at specified guage points and automate guage readings by minimizing human intervention thus increasing the accuracy and efficiency of monitoring system.
• It is an advanced technique to quantify water measurement at a particular location in a canal, these measurements are used for the operational managements of pumps and gates.

Digital Pulsed Doppler or ADCP
>contact type•Pulsed wave (PW) Doppler systems use a transducer
that alternates transmission and reception of ultrasound.
•One main advantage of pulsed Doppler is its ability to provide Doppler shift data selectively from a small segment along the ultrasound beam, referred to as the “sample volume”.
•The location of the sample volume is operator controlled.

Aqua Profiler
> Contact type•The system is designed to measure both, the vector and
the magnitude (using twin velocity beams) of individual velocity cells to account for velocity variations within the flow and obtain the flow profile.
•A third vertical acoustic or hydrostatic sensor beam is used to measure water level.

RiverSurveyor
• The patented and award-winning RiverSurveyor®, S5/M9 systems give a new perspective to the notion of measuring open channel hydraulics. Using SonTek's exclusive SmartPulseHD®, multiple acoustic frequencies are fused with precise bandwidth control for the most robust and continuous shallow-to-deep discharge measurements ever. A deterministic microcontroller expertly apportions the proper acoustics, pulse scheme, and cell size to get the highest definition possible so you can focus on the measurement, not the instrument setup. The system even has a vertical beam for precise channel definition and it's all designed to work intuitively.
Ultrasonic transmitters
> Non contact• operate by sending a sound wave generated from a piezoelectric
transducer to the surface of the process material being measured.
• transmitter measures the length of time it takes for the reflected sound wave to return to the transducer.
• successful measurement depends on the wave, reflected from the process material and moving in a straight line back to the transducer.
• factors such as dust, heavy vapours, tank obstructions, surface turbulence, foam, and even surface angles can affect the returning signal when using an ultrasonic level sensor.
13
Radar > Non contact• Working principle is similar to ultrasonic sensors.
• operation of all radar level detectors involves sending
microwave beams emitted by a sensor to the surface of liquid.
• electromagnetic waves after hitting the fluids surface returns back to the sensor which is mounted at the top.
• The time taken by the signal to return back i.e. time of flight (TOF) is then determined to measure the level of fluid.

CHALLENGES IN COLLECTING DATA
• The problem with manual measurements is that these are less accurate than automatic measurements and often cannot be completely reproduced.
• The first problem primarily has to do with entering data manually, while the second problem is caused by different colleagues in the field taking measurements in different ways
• People can cheat by sending information without being in the field based on their experience / guess.

With the MobileTracker, a water systems operator or hydrographer can take a field measurement by simply taking a picture; the rest is done automatically.
The Mobile Level Tracker allows you to measure water levels with the click of a button. The inaccuracy of the measurement is less than 10 mm when using a metric staff gauge and 0.15 inch when using an English staff gauge.

Ultrasonic and sonic instrumentsNon-Contact Water Level Sensors
http://www.stevenswater.com/water_level_sensors/non-contact_info.html
Both ultrasonic and sonic level instruments operate on the basic principle of using sound waves to determine fluid level. The frequency
range for ultrasonic methods is ~20-200 kHz, and sonic types use a frequency of 10 kHz. a
transducer directs sound waves downward in bursts onto the surface of the water. Echoes of
these waves return to the transducer, which performs calculations to convert the distance of wave travel into a measure of level. For practical applications of this method, you must consider a
number of factors.
