When using Heron dipperLog pressure transducers you are measuring absolute pressure or the pressure of everything exerting pressure on the dipperLog from above.  Barometric pressure is a component of that measurement.  Barometric pressure, often referred to as atmospheric pressure, is a very unstable value.  It can be affected by weather systems, seasonal changes and diurnal […]

Water Level Meters are only as accurate and reliable as the tapes they employ.  For that reason, Heron Instruments is always striving to ensure that the highest quality tapes are installed on their meters. All our tapes incorporate braided 7 strand conductors (4 stainless steel and 3 copper) to further strengthen the tape and prevent […]

Compensating with a barLog

Barometric pressure, often referred to as atmospheric pressure, is a very unstable value affected by weather systems, seasonal changes and diurnal shifts.  It is never a Static Value.  The resulting shift in daily barometric values can be in excess of the equivalent of 30cm or 12” of water. If you are monitoring water levels over […]

Interface meters are specialized water level meters designed to measure the depth and level of anhydrous phase fluids, both dense and light, as well as water.  The two principles used to determine these measurement are the light deflection caused by the fluids and the conductivity of water. When the probe touches the top of any […]

Compensating Data

Many people ask “Why do I need to compensate my data?” When using pressure transducers that measure absolute pressure, barometric pressure is a component of that measurement.  Barometric pressure is not a constant and must be subtracted from the pressure recorded to realize the actual water level. Barometric pressure is pressure exerted by the atmosphere […]
