Positive Displacement (PD) Meters
-
Positive Displacement (PD) flow meters are volumetric flow measurement instruments ideal for low flow rates, highly viscous fluids, and measurement of flows involving starts and stops or pulsing. Positive displacement flow meters are similar in design to the gear pump. The principle of operation is reversed however; instead of the gears driving the fluid, the fluid drives the gears. A non-intrusive hall-effect sensor detects the movement of the gear and as each gear tooth passes the sensor, a square wave pulse is produced and a discrete volume of liquid is measured. The resulting pulse train is proportional to the actual flow rate and provides a highly accurate representation of the fluid flow.

Partial Discharge
-
Partial discharge (PD) is a local electrical discharge that occurs in imperfections or inhomogeneities. The partial discharge measurement is a so-called “non destructive test” to determine the quality of insulating materials. On the contrary of pure high-voltage test, th test item is not pre-damaged at low PD levels.

Software for the Development and Implementation of Test Programs using IEEE 1641
newWaveX Suite
-
We Have a unique suite of tools to support the development and implementation of test programs created using IEEE 1641 to define the signals and tests. These include the entry-level version of newWaveX (newWaveX–Lite), the development versions of newWaveX (newWaveX–SD and newWaveX–PD) and the complete integrated development environment for IEEE 1641, SigBase. These tools provide everything necessary to work with IEEE 1641, from creating simple signals through to implementing and managing a complete 1641 test environment. All of our 1641 tools are commercial off-the-shelf (COTS) items that may be used stand-alone or integrated into a complete test development environment. newWaveX products may be integrated with third party test executives and associated software.newWaveX is an intuitive user-friendly suite of products that does not require specialist training for users to acquire the skills to develop 1641 programs. Completing the IEEE 1641 User/Developer training course (which uses newWaveX Signal Development for the hands-on element), together with the associated 1 day newWaveX–SD User/Developer training course, provides complete information for the newWaveX user. Further support is provided for users of newWaveX packages under the maintenance agreements for those products.
