The BulfroComm the data communicator, is a small self-contained unit in IP65

Grade case which connects to sensors in the field,

collects readings from those sensors, and transmits

the collected data to a central server via cellular

telephone network. This communicator is configurable

for time based data frequency, for different

communication protocol & can be configured to

different server addresses. Even fully bi-directional

communications are possible. Data storage is possible

in case of communication media loss up to 1GB.

Water level observations made during a aquifer tests are susceptible to distortions

due to the influence of ambient temperature and ambient pressure and local

gravitational acceleration. These distortions can be significant in aquifer test cases

where interference due to pumping effects are small, because barometric

pressure effects can make up a large proportion of the total observed water level

fluctuations It is therefore important to consider and correct for effects of

barometric pressure changes, temperature changes and location changes when

analyzing aquifer test water level data.

We have corrected all 3 main elements of distortion possibilities. These 3

possibilities are taken care with these innovative concepts and during the

product development.

WC – Water Column (m)

𝑇𝑎𝑚𝑏- Ambient Temperature/Water Temperature

𝑃𝑎𝑚𝑏- Ambient Pressure

𝑔𝑙𝑜𝑐𝑎𝑡𝑖𝑜𝑛- Gravitational Acceleration Location

The variation in ambient pressure changes the depth of water column. The

variation of ambient pressure with respect to temperature and altitude can be

seen as follows;

Borewell water temperature changes with ambient temperature. The effect can

be seen from the following diagram;

Temperature Profile with Respect to Ambient Temperature at Ground

The density of the water is a strong function of water temperature, the variation

can be seen from the table. The correction while calculating the water column is

must for accurate calculations.

The local gravity is dependent on several factors such as latitude, height above

sea-level, local geological density, etc.The gravity is important factor when Water

Column is calculated because gravity directly relates the mass of water column.

Though the default value of gravity is 9.80665 ms-2 which is standard gravity, the

variation can be observed as follows;

The formulas used by this calculator are based on the International Gravity Formula 1980 (IGF) which determines the gravity from the position of latitude, and the Free Air Correction (FAC) which corrects for height above sea level.

IGF = 9.780327 (1 + 0.0053024sin2Φ – 0.0000058sin22Φ)

FAC = -3.086 x 10-6 x h

g = IGF + FAC

g - Theoretical local gravity

IGF - International Gravity Formula

FAC - Free Air Correction

Φ - Latitude

h - Height relative to sea level
