- The relative simplicity of the ALMPD makes it far less costly than other PD flowmeters desigined for low-flow rate measurement.
- Reduced susceptibility to wear versus other PD technologies as a result of the following design features:o Micro-machined components with reduced size resulting in lower relative velocities amongst the moving partso Any forces acting on one side of the
- Since the moving parts are not rigidly attached to each other or the motion detection mechanism, the ALMPD is capable of service in fluids less filtered than other devices which may be capable of measuring similar low flow rates.
- Should the MICRO FLOWMETER become clogged with debris, it can be easily disassembled, cleaned and reassembled with reasonable care in the field.
