Water Level Transmitter of ULB3351 is one kind of scene transmitter with flange type for mounting in pipelines or vessels.

Because its isolating diaphragm contacts liquid medium directly, not need pressure pipe to draw out the pressure from positive pressure side (H side), therefore ULB-335 is suitable for level, pressure, density measurement of high temperature, macro viscosity, easy crystallized, easy precipitated media.

ULB3351 transmitter includes plane type and insert type. The mounting flange has 3” and 4” according to ANSI standard. If the user has any special requirement please indicate on ordering sheet.

The wetted part material of ULB3351 has SS 316L, Hastelloy-C 276, tantalum and Monel etc for options.

This water level transmitter is especially suitable for level, pressure and density measurement of special media (high temperature, macro viscosity, easy crystallized, easy precipitated, strong corrosion) in open or sealed containers.
Features
  • Measuring range：0 ~ 2.67 kPa...2500 kPa
  • For level, pressure, density measurement of high temperature, macro viscosity, easy crystallized, easy precipitated or strong corrosive media
  • Adjustable range: 6:1 for analog type, 15:1 for intelligent type
  • High accuracy, good reliability and stability
  • Intrinsic safety and flame proof option
