KS-SMY1 Hydrostatic Water Level Sensor
The Apure KS-SMY1 is a submersible hydrostatic sensor for continuous liquid-level measurement. Select the range and electrical output for the liquid, installation depth and receiving instrument.
- Submersible pressure measurement
- Level referenced to the probe
- Current or voltage output by configuration
Pressure and liquid height
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.
Probe placement and zero reference
Set the probe at the intended reference elevation and keep the sensing face clear of sediment and inlet jets. Check the wetted material and cable jacket against the liquid. If the ordered gauge-pressure version uses a vented cable, terminate the vent in a dry location and keep the air path open. At commissioning, compare the output at a known liquid level with the indicated value.
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. Confirm the materials, range, output and temperature limits for the supplied assembly.
