Flow Sensors
CMM 500 – High-precision measuring of compressor capacity
The CMM 500 can be used directly downstream of the compressor for measuring in wet compressed air, or as a compressed air meter for billing in dry compressed air.

1 / 2Mass Balance Flow Meters
MudMaster Mass Balance Flow Metering System
Spool-mounted system that measures drilling mud flow and density without touching the flow.
- Supplied and supported by GTi in Thailand
- Calibration certificate on delivery
- Selection, installation and commissioning help
Overview
Bolts into the outlet pipe with no obstruction and no pressure drop, giving real-time flow and density data.
- Application of non-contact and non-intrusive technologies for mud flow measurement under all partially full pipe flow conditions
Specifications
- Optimised for Gravity-Fed Mud Return Lines
- Designed specifically for non-pressurised outlet flow lines.
- Non-Intrusive, Non-Contact Measurement
- No flow restrictions, obstructions, or moving parts—minimising wear and maintenance.
- Accurate in Partially Full Pipe Conditions
- Delivers reliable flow readings even during variable fill levels.
- Independent Mass Flow Measurement
- Calculates mass flow using separate volume flow and density measurements.
- Integrated MudIn Inlet Monitoring
- Includes a high-pressure (5000 PSI) Coriolis meter on the inlet for real-time mass balance data.
