Wire

and Flex are intelligent liquid level sensors which can be installed in a vessel or in a standpipe. For the Wire sensor the

sensor element is a stainless steel wire insulated with PTFE and for the Flex sensor the element is a stainless steel wire

mounted with steel and aluminum tube elements to increase the sensivity. Both sensors can to be mounted directly in a

stand pipe. If they need to be installed in a vessel they need an inner pipe. Both sensors measure between the wire/tube

elements and the surrounding pipe.

The sensor can be installed in refrigeraon systems and similar demanding applicaons with high pressures and aggressive

uids. The sensor emits a 4-20mA analog signal, which is proporonal to the liquid level.

The sensors comes in dierent versions with or without a cable for direct valve control. All versions emits a 4-20mA analog

signal, which is proporonal or disproporonal to the liquid level, via the M12 plug. The sensors are available in special ver-

sions which contains a controller able to control a valve directly, without using a PLC.

Installation Instructions—wire sensor The wire sensor is designed for level measurement of liquids in vessels like, tanks, pump separators and receivers . The sensor can be mounted in a standpipe from 1” (25mm) up to 4” (100mm) diameter or directly in a vessel with an inner pipe from 1” (25mm) up to 4” (100mm) diameter. The inner pipe is needed to create sufficient measuring signal and to avoid a swinging wire in a lively fluid.

Stand pipe: DN32..…DN65. Recommended pipe standard: DIN 10220 Recommended bending: DIN 2615-1/Type 3 Recommended TEE: DIN 2615-1 Standpipe: DN65…DN100. Recommended pipe standard: DIN 10220 Recommended bending: DIN 2615-1/Type 3 Site pipe can be designed in smaller pipe e.g. o.5 x DN. Wire level sensor manual 07 June 2022 HBproducts.

Installation Instructions—Flex sensor The Flex sensor is designed for level measurement of liquids in vessels like, tanks, pump separators and receivers . The sensor can be mounted in a standpipe 1” (25mm) or 1 ¼” (32mm) diameter or directly in a vessel with an inner pipe 1” (25mm) or 1 ¼” (32mm) diameter. The inner pipe is needed to create sufficient measuring signal and to avoid a swinging wire in a lively fluid.
PAGE 6
Wire adjustment—Wire sensor The sensor is installed in the standpipe or directly in the tank. The sensor length is determined by standpipe length or tank height. Cut the insulated steel wire to desired measuring length with a wire cutters The counterweight is fixed by the wire with 2 screws. Liquid sealant is applied to the thread. L = Programmable sensor length L= Wire length Allow for 50 mm clearance below the weight to the bottom of the tank—if relevant. To install HBLT-wire, you must use a 2.
PAGE 7
Installation instruction—Flex sensor The sensor can be shortened to fit the standpipe length or vessel height. The sensor consist of a 5 mm steel wire fitted with a stainless steel weight at the bottom, plastic spacers and aluminum pipes. The purpose of the plastic spacers is to keep the metal parts away from the pipe and the aluminum pipe increase the sensitivity of the sensor. The sensor with all elements removed from the wire. To shorten HBSLT/HBLT-Flex, you only need to remove the necessary elements.

How to connect the sensor Two different type of sensors • A pure sensor version with 4-20 mA output • A controller version with both cable for direct valve control and analog output All sensors can provide a signal for a PLC via the M12 connection. The M12 connection is also used for power supply. Some versions are able to control a valve directly. They have a cable, which can be connected directly to the valve.

Basic settings Filter time averages the output over a period and reduce fluctuations Here you make the primary settings of the sensor Here you set the parameters for the control function. Here you set the parameters for the sensor. The wire sensor with the counterweight where the wire passes through, must use wire sensor mk3 When “Run in signal” is set to off the sensor control continuously when set to on, control only when signal is applied on pin5 Here you set the alarm level.

Advanced settings Here you make the advanced settings of the sensor Here you set the parameters for the alarm function. Only available for sensors without cable Here you can adjust parameters for the valve control Alarm relay function: Here, the relay function is indicated, depending upon the instructions – NO or NC (normally open/normally closed).
PAGE 16
Diagnostic (calibration of sensor) Here you make the calibration of the sensor. If the sensor is operating in one of the predefined liquid it is delivered with a calibration and does normally not need further calibration. If you need higher accuracy the sensor can be calibrated Here you can see and change the zero calibration.

LED indication • Green LED indicates 24 V DC supply; it flashes during operation. If "run-in" is not used, this function must be deactivated in the tool. • Yellow LED indicates control. The flashing sequence indicates if the valve is closing or opening. • Red LED indicates high- or low-level alarm, depending upon the setup. 3-digit display: (not available on /S stepper motor control version.) Showing 0…100 % linearly corresponding to 4…20 mA.

Fault detection General: In case of fault, it is normally enough to replace the electronic part. Fault Reason Correction of fault No LED is on / not operating. No supply to the sensor or defective cable/plug Check and find faults in the power supply, or replace the supply cable. Yellow and red LED flash. Power supply is not sufficient. Install proper power supply. Valve open and close to fast.

Quick guide Installation The sensor is installed in the vessel using liquid sealant or PTFE tape like shown in the manual and the electrical unit is connected. If the electronic unit has the threaded union, make sure it is firmly tightened to secure good electrical connection. Setup The sensor is delivered pre-calibrated for the liquid you specified when ordering and ready for use. To obtain a more accurate measurement you need to calibrate the sensor as described in the complete manual.
