The relative simplicity of the DEA liquid MICRO FLOW METER concept makes it substantially less costly than other positive displacement flow meters which may be capable of measuring similar low flow rates.
Compared to other positive displacement flow meters, the DEA Micro Flow Meter is less susceptible to wear. The reasons for this are as follows:
The parts are so small that the relative velocities amongst the moving parts are very low.
All forces acting on one side of the nutator are largely offset by the opposing forces acting on the opposite side.
The ends of the beam are rounded resulting in a rolling motion rather than sliding during operation.
Since the moving parts are not rigidly attached to each other or the motion detection mechanism, the Micro Flow Meter is capable of service in fluids less filtered than other devices which may be capable of measuring similar low flow rates.
Should the Micro Flow Meter become clogged with debris, it can be easily disassembled, cleaned and reassembled with reasonable care in the field.
