“QUANTOR-5est” stationary echometer

“QUANTOR-5est” monitors fluid level and gas pressure in the well annulus.
Two design versions of the instrument are available: stationary and mobile.

The “QUANTOR-5est” echometer generates an acoustic pulse without annulus gas bleeding to the atmosphere.

The “QUANTOR-5est” echometer can operate under vacuum, zero pressure and overpressure (up to 100 kgf/cm2) with its settings and design kept unchanged.

The instrument does not have a compressor, all connectors are protected by special caps which significantly increases reliability of the instrument under severe operating conditions.

“QUANTOR-5est” has a leak-proof design. The structural elements contacting with well head gas are made of corrosion resistant materials.

The stationary instrument receives power and transmits data to the telemetry controller via a special armoured cable. The electrical circuits belong to the intrinsically safe category.

The mobile instrument receives power from the internal batteries, and data are transmitted via Wi-Fi, cellular network or satellite communication network.

The instrument is equipped with a thermal cover for operation in the temperature range from — 40 С° to — 65 С°.
Data transmission
Data are transmitted from “QUANTOR-5est” as follows:
Via Wi-Fi to the reception and processing unit
Via a cable to the control cabinet (MODBUS-RTU (RS-485) or TCP/IP communication interface)
Via cellular network
Via IRIDIUM satellite communication channel
The “QUANTOR-5est” echometer complete with a GSM or IRIDIUM module allows receiving and processing the measurement results right in the office without a well visit.
