WATERLINE CONTROLS

WATERLINE CONTROLS is a manufacturer of fluid level controllers designed for industrial water and wastewater management applications. The brand's product line centers on relay-based control units that manage pump fill, high alarm, and low alarm functions in tanks, basins, and reservoirs. These controllers are built to operate in demanding environments, with all listed models carrying a NEMA 4X rating, indicating protection against corrosion, dust, and hose-directed water—suitable for indoor and outdoor installations in washdown areas or corrosive atmospheres. The controllers accept input voltages of 110/120V AC or 220V AC, and each unit features DPDT power relays rated at 30 A, with dry contact outputs ranging from 2 to 5 contacts depending on the model. The product family includes three core series: the WLC3000 series (single-function fill control with one power relay), the WLC4000 series (fill/high alarm with two power relays), the WLC5000 series (fill/high alarm/low alarm with three power relays), and the WLC6000 series (fill/high alarm/low alarm with four power relays). Each controller is supplied with a specific probe configuration—reference, fill stop, fill start, or low alarm probe—depending on the model and function set. The controllers operate on a conductance-based sensing principle, using the conductivity of water to detect levels, which makes them suitable for clean water, wastewater, and many process liquids. 3G Electric stocks multiple SKUs across the WLC3000, WLC4000, WLC5000, and WLC6000 series, covering both 120V AC and 220V AC variants. This allows procurement specialists and plant engineers to select the exact control logic and voltage required for their application without custom modifications. The NEMA 4X enclosures eliminate the need for additional protective cabinets in many installations, reducing total system cost. For maintenance managers, the modular relay design simplifies troubleshooting and replacement. 3G Electric provides logistics support for these controllers, ensuring availability for projects ranging from single-tank retrofits to multi-pump station upgrades.

Pertanyaan yang Sering Diajukan

Pertanyaan umum tentang WATERLINE CONTROLS dari 3G Electric.

What is the difference between the WATERLINE CONTROLS WLC3000, WLC4000, WLC5000, and WLC6000 series?

The WLC3000 series is a single-function fill controller with one power relay and two dry contacts. The WLC4000 series adds a high alarm function, using two power relays and three dry contacts. The WLC5000 series includes fill, high alarm, and low alarm functions with three power relays and four dry contacts. The WLC6000 series provides the same three functions but with four power relays and five dry contacts, offering additional switching capacity for larger pump systems.

What NEMA rating do WATERLINE CONTROLS fluid level controllers have?

All WATERLINE CONTROLS models listed by 3G Electric carry a NEMA 4X rating. This means the enclosure is weatherproof, corrosion-resistant, and suitable for indoor or outdoor use in environments exposed to water, dust, and corrosive agents. It is not rated for submersion.

What probe configurations are available with WATERLINE CONTROLS controllers?

Probe configurations vary by model. For example, the WLC3000-120VAC includes a reference probe, while the WLC3000-220VAC includes a fill start probe. The WLC4000-120VAC comes with a fill stop probe, and the WLC4000-220VAC includes a reference probe. The WLC5000-120VAC includes a fill stop probe, and the WLC5000-220VAC includes a low alarm probe. The WLC6000 series units include a reference probe. Always verify the included probe type for your specific SKU.

Can WATERLINE CONTROLS controllers be used with liquids other than water?

These controllers use conductance-based sensing, which requires the liquid to have sufficient electrical conductivity to complete the probe circuit. They are designed primarily for water and wastewater. For non-conductive liquids or those with very low conductivity, alternative sensing methods such as ultrasonic or capacitive level controls would be more appropriate.

What is the maximum relay contact rating for WATERLINE CONTROLS controllers?

All models feature DPDT power relays rated at 30 A. This rating applies to resistive loads. For inductive loads such as motors, derating may be required. The dry contact outputs are rated for the same 30 A DPDT configuration, providing direct switching capability for pumps up to the relay rating.

Does 3G Electric stock both 120V AC and 220V AC versions of WATERLINE CONTROLS controllers?

Yes. 3G Electric carries multiple SKUs for each series in both 120V AC and 220V AC input voltages. For example, the WLC3000 is available in 120V AC (SKU 4GHK3) and 220V AC (SKU 4GHK8). The WLC4000, WLC5000, and WLC6000 series are similarly stocked in both voltage options.
