1Main specifications

Material

Polyamide-based (PA) technopolymer, grey colour.

Packing rings

  • TPE flat gasket (HFL-EF).
  • NBR synthetic rubber O-Ring (HFL-ER).

Connector with sensor block

Right side output including protection against water sprays (protection class IP 65 according to EN 60529 table).

For a correct assembly see Warnings.

Dipstick

AISI 304 stainless steel tube, fastened to the body by a nickel-plated brass coupler.

Float

NBR synthetic rubber.

Standard executions

  • HFL-EF: assembly by means of a flange with 3 holes at 120° for 3 zinc-plated steel screws with hexagon socket, supplied. It can be assembled also with 2 holes at 180°.
  • HFL-ER: assembly by means of a 1"" Gas threaded coupler.

Maximum continuous working temperature

80°C.

2General information

Features and applications

HFL-E rapid levels show a minimum or maximum default level, according to the application needs.

Highly versatile, these rapid levels allow to define the most accurate set point by simply disassembling the dipstick float and cutting the dipstick exactly where needed, according to the specifications shown in the table.

Free from magnetic parts, the float is integral to the dipstick making this level indicator ideal for use in tanks containing dirty liquids, water, oil, coolant oil, also with iron metal parts or foams. Moreover, the operation is independent of the fluid electrical conductivity.

To ensure utmost safety, the electrical components are separated from the tank and perfectly sealed by means of ultrasound welding.

Two-pin connector assembly instructions

  1. Remove the connectors from the indicator by unscrewing the set screw placed in the bottom, take the contact holders out and loosen the cable glands.
  2. Slip on the two-pole cable into the connectors (standard connectors) and connect the wires to the terminals nr. 1 and nr. 2 of the relative contact holders.
  3. Assemble by pressing the contact holders into the realtive connectors in the required position.
  4. Screw the connectors to the indicator and then tighten the cable glands.
