Water is very precious for next decade globally and big

challenge to meets the demand for Industry, Irrigation and

Drinking.

World Bank is funding for Modernization and upgrade the

Hydrological Measurement Techniques, Automation and

their Implementation in India as well as other Countries.

The aim is to get quality Hydrological data which can be

utilized for the Model’s for regulating Water in Precise &

Smart way.

Automation of water management system will contribute

toward flaw less availability of water to USER with optimize

man power deployment and integrated information at local

and central office’s

Advantages of Siphon Tipping Bucket Rain Gauge

Siphon based Rain Gauge minimize the impact of different

rate of rainfall.

Siphon based Rain Gauge can be calibrate for different

rate of Rainfall intensities where as Non Siphon only for one

rate of Rainfall intensity.

They prevent spreading of water drops outside the

bucket by release the rainfall water straight and allows

controlled flow to bucket.

With “Dual Reed Switch” the TBRG can minimize field

maintenance work and can connect to parallel system too.

Features of TBRG Sensor for Snow Area (With Heater Kit)

•All Die-Cast Aluminum construction (perfect anti corrosion)

makes it sustains in snowy condition better than other TBRG.

•The heater kit underwent testing in an operating temperature of

-20C (snow) with 35W to melt such iced snow.

•The kit has TWO elements (one to melt snow/ice in the

catchment) another to ensure water in the bucket is kept in an

unfrozen state for not only measurement but discharge of water

on each tip of the bucket.

•TB3H/LP has a ‘sensor’ to detect precipitation in the catchment

(so it only operates when snow is detected) which save power in

the remote area.

•Operate on 12 - 24 VDC or from a 12 - 24VAC power supply.

WATER FLOWCurrent Meter Counters

Counter CMC20A [A counter only to display propeller (or cup) revolutions over a pre-set interval (hung around the neck)]

Pointing Velocity Display

PVD100 / 200 (A counter to display propeller (or cup) revolutions over a pre-set interval PLUS calculate and display ‘point velocity’ once the calibration equations for the current meter are entered. (hung around the neck))

Gauging Computer

CMC3 Hydromate (A paperless computer hung around the operators neck. Distance and depth can be entered via a touch screen, are and point velocity are logged and total discharge estimated. Data downloadable at the end of the day to a laptop or desktop in CSV format!)

Cable Fox

Cable Fox system is the latest innovation forpositioning an ADCP on a new or existingcableway.

Cable Fox operate on steel cables from12.7mm to 28.5mm dia with Traversingspeed adjustable from 0.01m/s to 0.80m/s

Hoist motor available as an option (100kg )lifting capability

Advantage of Constant & Dry Bubbler System

•The pressure in a bubbler system should always be maintained in

the orifice line for accurate measurement.

• Constant bubbler ensure bubbles are continuously being pushed

out of the river line and a level measurement can be taken at any

time.

• Non-constant bubblers turn off in between measurements & it

can take up to 15 minutes for the pressure stabilization in line.

• Dry Bubblers free from trapping airborne moisture and ensure

reliable measurement with free from Desiccant Cartridge i.e.

Maintenance free & no recurring cost to user.

• Trapped moisture in the lines of the bubbler, causing ongoing

data errors until the complete river line is replaces.

Issues for modernizing data procurement methodologies

There is need of Improved Technology based Equipments

/ sensors having least maintenance with workmanship to

ensure longevity field operation of sensors. (10 years).

Proper & correct specification of desire sensor / system

with inclusion of “Sensor Design Technology” in the

Technical Specification.

Proper price estimation of the Each System Component /

Parts.

Specification Ensures for quality data from sensor in the

operational system.

30

Suggestion for modernizing data procurement methodologies

The ability of Rainfall sensor to sustain in heavy rainfall

event with accurate data during variable intensive

rainfall event.

Preferred Constant Bubbler (True Bubbler) Water Level

Sensor, which maintained continuous pressure in the

orifice line, for reliable water level for big span Indian

Rivers during flood event.

Field camera support by logger as component of system

to see the facts of the site in real time.(May be focus to

Gauge post, Gate position)

31

Suggestion for modernizing data procurement methodologies

The data should be transfer from field directly over

End User email addresses and ftp addresses of servers to

ensure receive of “original field data” via GSM /GPRS

Telemetry (Cheaper & No complexity than INSAT

Transmitter).

Satellite Modem (works with Polar Orbit Satellite

constellation i.e. Iridium Satellites) may be approve by

Govt. of India for special services like Water Sector

monitoring with dedicated frequencies, so very remote

places data can be obtain easily..

CONCLUSION

Hydrological Services ongoing R&D

program will continue to provide

water cycle measurement and

monitoring solutions for a wide range

to clients World wide
