The Sponsler T675 cryogenic totalizer built a reputation as a rugged, dependable totalizer for low-temperature liquid measurement, especially in LOX/LIN/LAR and LNG transfer. With that model discontinued, Turbines, Inc. developed the CDS1000 as a direct, modern replacement—preserving what users liked about the T675 while adding the reliability, configurability, and serviceability today’s operations expect.
Direct Replacement Functionality
Functionally, both devices serve the same purpose: taking the pulse output from a flow sensor (in this case specifically a turbine meter) and converting it into a stable, readable total for custody transfer or inventory control. The CDS1000 matches that core behavior so you don’t have to re-engineer your process to keep measuring. In retrofits, installers can reuse mounting locations, with similar hardware, minimizing downtime and avoiding costly panel rework. Turbines, Inc. designed the CDS1000 specifically with “drop-in” in mind: the physical footprint, terminal layout, and signal expectations are aligned to what T675 users already have in the field.
Where the CDS1000 excels is in usability and lifecycle confidence. Expect a clearer, more informative display with intuitive menus for configuration, so technicians can set K-factors, scaling, and pulse logic without digging through legacy manuals. Modern electronics deliver better noise immunity and temperature stability—important when your instrument sits near cryogenic lines, where thermal cycling and EMI can wreak havoc on older totalizers/counters. Parameter retention and built-in diagnostics help crews confirm correct wiring and signal quality on the spot, reducing troubleshooting time.
Integrate Into Existing Cryogenic Systems
On the integration side, CDS1000 offers flexible output options so it can link with both local operators and plant systems. You get totalization that’s easy to read at the skid, plus pulse or frequency outputs for PLCs, batch controllers, or DCS historians—maintaining continuity with how the T675 was typically wired while enabling cleaner data capture. Configuration locking and password protection support good metrology practices.
Maintenance and support are another clear advantage. With the T675 discontinued, sourcing parts and expertise becomes progressively harder. The CDS1000 is actively manufactured and supported by Turbines, Inc., so replacement units, accessories, and technical help are available from a single, accountable supplier. That reduces obsolescence risk and simplifies audits and spare-parts planning. Documentation, wiring diagrams, and quick-start guides are current and consistent, which matters when you’re training new technicians or standardizing across multiple sites.
Consideration When Replacing Sponsler T675
For operators planning a changeout, think of the CDS1000 as a like-for-like swap that also modernizes your panel. The practical path is straightforward: note your existing meter’s K-factor and pulse pickup type, record the scaling and any relay/output settings from the old unit, power down, swap to the CDS1000, and re-enter those values. Most facilities report immediate familiarity and minimal commissioning time because the CDS1000 was intentionally built to mirror the T675’s role in the loop.
