Flowmeter Sondes
The Geovista flowmeter probes can be used on their own or in combination with other Geovista sondes

Impeller Flowmeter: Different size impeller cages can be interchanged to suit different pipe or borehole diameters.

Specifications:
Weight / length: 3.5kg / 0.48m
Cage Diameter: Optional interchangeable impeller cage sizes to order.
Typically: 50, 70 and 100mm
Threshold Velocity: Varies with cage size. (Typically 1 m/min with 50 mm cage)
Resolution: 1/40th turn
Data output Flow rate, direction
Max. Pressure: 20MPa
Max. Temp.: 80ºC

Heat-Pulse Flowmeter: This sonde is used for applications where the flow rate is below the threshold of the impeller

Specifications:
Weight / length: 6.2kg / 0.9m
Sonde Diameter: 51 mm
Measuring range: 0.1 to 3 m/min
Resolution: 0.1s
Data output Time, Direction
Max. Pressure: 20MPa
Max. Temp.: 80ºC

Fluid Sampler Sonde
The Geovista Fluid Sampler is capable of retrieving both gas and liquid samples at downhole pressure conditions. A variation that is suitable for sampling dissolved trace gasses includes a downhole circulating micro-pump to avoid sample contamination.

The probe can also be fitted with a water level indicator. Further correlation can be established by combining the sampler with other Geovista sondes like a Gamma Ray and / or a CCL sonde.

Specifications:
Weight: 3.0 kg
Length: 0.45 m
Diameter: 44 mm
Sample Volume: 1/3, 1/4, 1/2, 1, 1.5 and 2 Litre to order
Max. Pressure: 20MPa
Max. Temp.: 80ºC
