The ±10mm accuracy across a 6000mm measuring range is actually tighter than most people expect from a float-based system, especially when you're dealing with oil tanks that can shift around in temperature.
We've been using these for about two years now across several tank farms, and what really sold us was the custom length option — we ordered one at 4800mm for a specific diesel storage tank and it fit perfectly with no adapter plate needed.
Pressure rating goes up to 32MPa which is honestly overkill for most oil application (usually 1.0-10MPa is plenty), but it means you don't have to worry about derating at higher temps up to 480°C, and the 4-20mA HART output is pretty much standdard for our DCS integration.
The one thing nobody tells you is that the float density adjustment — we had to tweak ours from 0.42 to 0.55g/cm³ for a heavy crude application — is a bit of a hassle if you don't specify it upfront, but suplier handled it in about 10 days or so.
We typically order through our procurement team with a 30-day lead time, and they've been consistent on delivery, though I'd recommend confirming the process connection type early because flange size can vary wildly between tank manufacturers.
Anyway, for most oil storage work the SS 316L option is fine, but if you're dealing with sour crude or high-sulfur environments, teh Hastelloy or PTFE-lined versions are a better bet — we learned that one the hard way after a pitting issue on a 12-month-old unit.
Our MOQ is typically 10 units for standard models, but we can work with smaller quantities for custom OEM orders—just let us know your needs.
Lead time for custom specs like a 6000mm Hastelloy gauge is around 15-20 working days after order confirmation, depending on current production load.
Yes, we include CE compliance documents by default. We can also provide material test reports for SS 316L, Hastelloy, or Tantalum upon request at no extra cost.
Absolutely, we can customize the float density from the standard 0.42g/cm³ to match your oil density—just specify the value when ordering.
Yes, the 4-20mA HART output works across the full pressure range from 1.0 to 32MPa, as long as the process connection is compatible with your system.
