Water-Level Automation Beyond 100 Metres: Wired or Wireless?
Mohit VekariaShare
When a tank is more than 100 metres from the pump panel, check the complete signal arrangement before selecting a water-level controller. Mohit Vekaria confirms that VUKAR offers customized wired and wireless water-automation solutions for long-distance applications. The suitable design depends on the actual site.
The distance is part of the control requirement
A level sensor may be at the tank while the starter is beside the pump. The control system must reliably carry the relevant level information between them.
Do not treat 100 metres as a universal limit for every standard controller. Use the exact manufacturer's documented cable or communication limits. A standard product with an unspecified range should not be assumed suitable simply because its start/stop functions look right.
What a wired proposal should establish
Record the full cable route, not just the straight-line distance. Ask the designer to specify the approved cable, sensor/interface arrangement, installation requirements and supported total distance.
A customized wired solution may be appropriate where a practical route is available. It does not follow that extending an ordinary sensor cable will preserve its documented operation. Use the approved complete arrangement.
What a wireless proposal should establish
Wireless level automation needs an assessed communication path and a suitable power arrangement at the remote equipment. Buildings, tank position and site conditions must be part of that assessment.
Confirm the actual communication method, usable site distance, any power or service requirements and what happens when communication is lost. “Wireless” does not by itself establish SIM use, internet dependence or a guaranteed range through every obstruction.
Keep the starter and communication roles clear
The remote link carries the required status or command. The motor still needs a compatible starter panel with the documented protection and switching arrangement.
Specify the normal filling sequence, tank-full stop and source-water requirements. Then confirm how a missing or invalid remote signal affects operation. A fail-response requirement in the brief is not evidence that a particular custom design already implements it.
What VUKAR needs to specify the solution
Provide tank and pump locations, approximate and routed distance, motor nameplate, available power and whether laying cable is practical. Include the intended source/destination sequence and any additional tanks.
The final proposal should identify the supplied equipment, agreed operating distance, installation conditions and commissioning checks. Test both normal level response and the documented communication-loss behaviour.
The benefit is making the required tank automation practical across the site's distance. If an existing standard arrangement already supports that distance and performs correctly, a customized replacement may be unnecessary.
