level recorder

The river flows are monitored using a river level recorder.

Weekly data on the ground water level were recorded using water level recorder.

A loud noise is produced, and as the sound dies away the trace on the level recorder will show a distinct slope.

An automatic water level recorder then will be installed on the well to record continuous water level changes using 30-day charts.

Groundwater level recorders have been installed in 7 drilled bores with water level available from about June 2000.

The monitoring technology is currently a mix of aging analogue water level recorders and modern digital recorders.

This agreement among them was also due, in conjunction, with a chart which was made by the automatic water level recorder located on the dam's center section.

For this reason, stream piezometer SP2/02 was equipped with an automatic water level recorder to evaluate any possible ground water/surface water interaction.

An error in the automated Sooke Reservoir water level recorder has resulted in previously reported spillage quantities being overstated.

Besides the first water level recorder, the company invented several other innovative pieces of equipment, such as the Telemark water recorder which was patented in 1939.

Brüel was instrumental in the construction of the level recorder, which would become one of the most successful products for his company Brüel & Kjær.

A water level recorder was deployed inside the marina to measure oscillations, and spectral analyses of the data were performed to determine any seiching frequencies present over time.

Historically reverberation time could only be measured using a level recorder (a plotting device which graphs the noise level against time on a ribbon of moving paper).

In 1911, Leupold & Voelpel was contracted by John Cyprian (J.C.) Stevens to manufacture a water level recorder he had designed and patented.

WHAT TO LOOK FOR: Buy a CO detector with a digital display that has a peak level recorder, which tracks the highest readings, and a battery backup, Morley said.

Originally the company's product range involved mainly mechanical devices, such as the Sherlock Pressure Sensing Unit and the A.U.S.1 Strip Chart Water Level Recorder, Sediment Samplers, Columbus Weights etc.

There was and remains a difference of professional opinions on the amount of time that elapsed, shown by the chart made by the Stevens automatic water level recorder, from when the line indicating the reservoir level broke sharply downward until it became perpendicular.

The use of dedicated light level recorders for tracking birds was pioneered in the 1990s by engineers and scientists at the British Antarctic Survey (BAS) who first developed a device in an attempt to record the movements of juvenile wandering albatross during the many years between fledging and returning to their colony to breed.
