KS-SMY2 Water Hydrostatic Level Transmitter
The Apure KS-SMY2 is a submersible hydrostatic transmitter for continuous liquid-level measurement. Use the output configuration that matches the receiving display or control system.
- Continuous hydrostatic measurement
- Level scaling for the liquid density
- Output matched to the receiving system
How the transmitter infers level
The probe measures the pressure at its sensing diaphragm. In a vented vessel, the hydrostatic pressure is p = ρgh, where ρ is liquid density, g is gravitational acceleration and h is the liquid height above the diaphragm. A density change shifts the indicated level unless compensated. If gas pressure acts on the liquid surface in a closed vessel, use a measurement arrangement that also accounts for that pressure.
Installation and signal checks
Choose a stable probe location away from pump intakes, inlet jets and areas where sediment may bury the sensing face. Secure the assembly using the supplied mounting method. Check the wiring and scale the receiving input to the ordered output and level span. For a vented version, protect the reference vent from moisture. Compare the reading with an independent level reference during commissioning.
The earlier overview and specification entries are listed separately below. The earlier overview refers to a low-copper aluminum alloy junction box, a stainless steel probe, 316L medium compatibility, and polyethylene, stainless steel tube and PTFE cable options. Verify the supplied materials, output and wiring before installation.
