Reservoirs, channels and sumps may have wind, rain, sun exposure and changing water surfaces.
Wastewater pits often need both continuous level and independent high-level alarm.
Wells and reservoirs may need long cable runs, surge protection, solar power or RS-485/4G telemetry.
Grease, sediment and foam can affect ultrasonic echoes and submersible probe diaphragms.
WELK compares radar, ultrasonic, hydrostatic and switch options from the actual water structure.
4-20 mA, RS-485, relay and display/controller packages can be configured for pump panels.
Medium, depth, mounting, cable length and power details are checked before model recommendation.

For wells, send total depth, static water level, pump drawdown, borehole ID and required cable length.
For open channels, send flume or weir dimensions, maximum flow, sensor mounting height and required output.
For wastewater pits, describe foam, grease, sludge, turbulence and whether an independent high-level switch is required.
Operating limits vary by medium and installation - values above are typical ranges, confirmed per project.
Ultrasonic, hydrostatic and radar instruments are selected by sump depth, foam, vapor and output requirements.
Radar or hydrostatic probes are common choices. The best option depends on mounting, range, power, telemetry and maintenance access.
A transmitter normally sends level to a controller or PLC. A display/controller package can provide relay outputs when simple pump logic is needed.
It can be good for open sumps when foam, vapor and turbulence are manageable. Heavy foam may require radar or a pressure probe.
Send well depth, borehole diameter, water level range, cable length, output signal and installation photos if available.
