924B Magnetostrictive Probe

 

All stainless-steel construction, highly accurate, easy installation and trouble-free performance for inventory management and in-tank leak detection.

The Model 924B Magnetostrictive Probe features standard stainless-steel construction, making it ideally suited for use with gasoline, diesel, ethanol and biodiesel. The 924B probe is certified to meet or exceed the U.S. Environmental Protection Agency’s performance standards for 0.1 gph (0.38 L/hr) volumetric tank tightness testing and 0.2 gph (0.76 L/hr) monthly product-level monitoring.

Features & Benefits
  • Accurate - Five-point temperature sensing element provides exact temperature compensation for product volume contraction and expansion, allowing for accurate inventory management and in-tank leak detection
  • Easy-to-Use - Automatically transmits probe profile to SiteSentinel® iSite™ on start-up, eliminating programming errors
  • Installation - Adjustable probe head centering disks provide a tight fit inside risers with diameters ranging from 2" (5.1 cm) to 4" (10.2 cm)
  • Compliance - Supports programmable ALD (Automatic Leak Detection) to perform daily, weekly, monthly, and annually required leak tests for 24-hour continuous monthly leak tests (for SiteSentinel® iSite™ only)
  • All stainless steel construction
  • Welded construction – eliminates potential leak points
  • Level 1 probe - one probe for all applications
  • Easy Installation - Fits in a 2-inch to 4-inch (5.1 cm to 10.2 cm) riser
  • Can be multi-dropped – up to four (4) probes connected on a single I.S. channel (SiteSentinel® iSite™/Integra 100™ only)
  • Optional Density Float - provides a measure of all changes in product density within the specified API density range
