About the product — UK-71 Dry-Reed Liquid Level Controller, 4 Points
The UK-71 Dry-Reed Liquid Level Controller, 4 Points is part of the ELEHPD float switch range, manufactured in Yueqing, Zhejiang, China and supplied factory direct to distributors, wholesalers and panel builders. ELEHPD float switches are used in tanks, pits, sumps, sewage water and pump control, and are built to IEC/EN standards with CE marking.
The UKY series is the workhorse cable float switch and the basis of the ELEHPD float switch range. A moulded polypropylene body carries a steel ball and a sealed microswitch; as the liquid rises the float tilts and the circuit switches, starting or stopping a pump, opening a valve or raising an alarm. The float hangs from a flexible PVC or HO7RN-F cable with a polypropylene counterweight, and the switching level is set simply by sliding the counterweight along the cable — one screw, no tools. Rated 250 V AC with 380 V maximum isolation, or 120 V AC for 110/120 V export markets, in 16 A (8 A), 10 A (8 A) or 10 A (4 A) versions; protection IP68CS for permanent immersion; working temperature 0 C to 80 C with the product rated to 70 C; mechanical endurance over 100,000 cycles and electrical endurance over 50,000 cycles. Five float shapes (trapezium, rectangle, large circular, small circular, ellipse) and five body colours (red, yellow, blue, grey, black) can be ordered, and the 3-core black / blue / brown cable gives both pump-down and pump-up wiring from the same float. ELEHPD factory direct, for clean water, wastewater, mild acid and alkali, and light industrial process duty. The UK-71 is a dry-reed liquid level controller built from a level probe and a display / relay meter. The probe uses a dry-reed relay, so it measures both conductive and non-conductive liquids, and the meter handles level display, alarm and pump control for open or closed vessels and underground water pools. Measuring range is 5500 mm and below with a 130 mm blind area, in 2 / 4 / 10 / 50 measurement points, with a 220 V AC 0.5 A output and a probe flange to GB2551-81 KN125 PN6. Because the sensing element is a probe rather than a float, there is no moving part in the tank and nothing to seize up in sludge.
Typical applications
Automatic pump control and level alarm in water tanks, cisterns, water towers, swimming pools, wells, sumps and sewage pits, plus light process vessels in food and drink, textile, chemical and metal finishing. Use the black-and-blue pair for drain-down pump control and the black-and-brown pair for fill-up. Pumps above 750 W / 1 HP and any three-phase motor must be driven through an AC contactor coil (A1/A2) — the float switch only provides the control signal. Read from a central control room.

How to specify the right float switch
When specifying, give us the rated current, the breaking capacity, the number of output points, the switching voltage and current, the mounting method and the cable length. Our engineers will select the matching model for your specification or against a sample.
