MIKON-101 Echometer + dynamometer system
Overview
System MIKON-101 is designed to determine the liquid level depth and measure the casing pressure and for the routine dynamometer monitoring of wells with a submersible pump.
The software Measurements Manager is shipped with MIKON-101 system.
Functions
- Liquid depth metering;
- Dynamogram and valve leakage testings;
- Quick display of echogram and dynamogram by the registration unit;
- Automatic measurement date and time recording;
- Saving measurements in non-volatile memory;
- View saved measurements;
- Transferring measurements to PC.

Units of the system
Registration unit RU-21
Registration unit is designed for registration, calculating and storing echograms and dynamograms. It has graphic display and keyboard. Power supply is AA type accumulators or non-rechargeable batteries. Protecting cover and built-in display heating system, spare accumulator set and charger is included.
Registration unit RU-21T
RU-21T improvements
- More robust and handy universal sensor connector.
- Larger memory size.
- No mechanical switches.
- More user-friendly UI and more powerful firmware.
- More keys.
- Higher PC connection speed (USB).
Acoustic signal reception unit ASRU-22P
Acoustic signal reception unit is designed to convert acoustic signals into electric signals and pressure metering. It has piezoelectric microphone, durable against hydrosulphur gas.
Polished rod transducer DN-117T
The transducer is clamped to the polished rod below the carrier bar and is designed for:
- metering relative load on polished rod;
- metering polished rod walk.
Cramping screw is used for optimal cramping force adjusting.
Acoustic signal generation unit ASGU-25
Acoustic signal generation unit is designed to generate acoustic signal in wells without exceeding pressure. It may be used for echo testing depth up to 600 m.
Extra equipment
Horseshoe transducer DV-118
Horseshoe transducer is mounted between traverses of the pump unit hinge and allows to measure absolute load values exerted on the polished rod. The hoisting jack is used for mounting the transducer. CAUTION! Before mounting transducer, stop the pump unit drive.
Threaded hoisting jack
Threaded hoisting jack is designed to move apart the traverses and mount horseshoe transducer.
Acoustic signal generation unit ASGU-26
Acoustic signal generation unit is designed to generate acoustic signal in wells without exceeding pressure. It may be used for echo testing depth up to 3000 m.
