  • Page 4: Field Of Application

    1. Field of application The float level sensors BLM-SF-FM are very precise, float controlled level sensors for continuous detection of liquid levels. The sensor BLM-SF-FM is designed for bypass applications. Features: • sensor pipe hermetically sealed against medium • free of wear and tear •...
  • Page 5 1.1 Principle of operation Inside the sensor’s pipe, a wire of magnetostrictive material is placed. Periodically, a current impulse is sent through the wire, which in turn cre- ates a circular magnetic field around the wire. This pulse starts a time measurement.

    3. Commissioning 3.1 Completeness of product …has to be checked during unpacking. If not otherwise ordered, the prod- uct travels on risk of the customer. Eventually occurring transport damag- es have to be indicated instantly with documentation according to the legal rights..
  • Page 8 Hints for handling inflammable media under pressure: It must be absolutely guaranteed that when an increase of pressure occurs, no gas-air mixture is present. On the one hand, the explosion prevention measures apply only under atmospheric conditions, on the other hand, with increasing pressure both the temperature can rise (adiabatic com- pression) and the ignition temperature becomes dramati- cally smaller.

  • Page 10 Electrical connection: Use a shielded two-wire cable with a cross section of 22…12 AWG. Crimp-on ring or spade terminal is required. Field wiring must be rated >10K above the equipment ser- vice temperature of +79°C. For maintaining ingress protec- tion IP67 the outer diameter of the cable has to be 7…10mm.

    4. Operating Instructions 4.1 Controls For usage, the front housing cap has to be unscrewed. An 8-digit alpha- numeric LCD is available for optical control of the settings. During normal operation, it shows the current measured values. The display has 8-digit alphanu- meric characters.
  • Page 12 4.2.1 Menu structure The 4-20 mA settings can be changed via the operating menu. Hereby, the offset (4 mA) and the span (20 mA) can be adjusted. WIKA Operating Instructions Level Transmitter – BLM-SF-FM...
  • Page 13 4.2.2 Extended menu All important parameters, as available via HART®, can be adjusted. Access: Press and hold all three buttons <+>, <-> and <OK> until “SET- UP” appears. Remark: if write protection is enabled (see 4.2.2.14), the sensor asks for the password.
  • Page 14 4.2.2.1 Adjustment of the offset The offset (4 mA-point) of the analogue output is adjustable. When setting the offset, the distance to the span remains constant. Available functions and their use are: Function Description Set the offset to Access: Setup -> 4-20 mA -> Offset the current meas- urement value of ->...
  • Page 15 4.2.2.3 Adjustment of the transfer function The characteristic curve of the analogue output can be selected. The cor- relation between the PV range and the analogue 4-20 mA value is calcu- lated by a transfer function PV (x) -> analogue output (a). The digital, via HART available values are not altered by this function (except the current value).
  • Page 16 4.2.2.4 Setting of the alarm current The current of the analogue output in case of sensor failure can be select- ed. The alarm current is set, if the sensor detects no float or the electron- ics detects a critical failure. Access: Setup ->...
  • Page 17 4.2.2.6 Calibration of the analogue output (DAC) The current output of the transmitter is controlled internally by a digital-to- analogue-converter (DAC). This DAC is calibrated ex works. If deviations of the set current from the measured current are visible, they can be cor- rected.
  • Page 18 4.2.2.7 Selection of the polling address The HART® polling address can be selected. Hereby, it is possible to sup- ply multiple transmitters with a single current loop. Every transmitter then can be queried by its unique address. Access: Setup -> HART -> Address 0…63 (Standard value: 0) Possible Values: Remark:...
  • Page 19 4.2.2.8 Selection of the multidrop mode The multidrop mode of the transmitter can be selected independently from the unique address. When activated, the loop current of the transmitter is fixed to 4 mA. Access: Setup -> HART -> Multidrop Possible Values: On, Off (Standard value: Off) 4.2.2.9 Selection of the multidrop mode The measurement values of the sensor can be damped exponentially.
  • Page 20 4.2.2.10 Using the PV simulation mode For diagnostics purpose of the connected process control system, it is possible to simulate an arbitrary measurement value without moving the float physically. Hereby, external switching functions and cabling can be tested. Access: Setup -> 4-20 mA -> PrimVar -> Simulation -100 …...
  • Page 21 4.2.2.12 Setting of the units The unit, in which a measurement value is calculated and displayed, is selectable. The setting applies for both display and digital values which are transmitted via HART®. Access: Setup -> HART -> Units Possible units are (availability varies acc. To the chosen channel): Unit Short form Code...
  • Page 22 4.2.2.13 Trim of measurement values It is possible to adjust a measurement value if it deviates systematically and reproducible from the set value. Therefore, a precisely defined pro- cess condition has to be established. Then, it is entered in the trim menu. Access: Setup ->...
  • Page 23 4.2.2.14 Enabling and disabling of the write protection The transmitter can be protected against accidental parameter changes. Hereby, all parameter changes via HART® are denied and the entry to the setup menu is protected by a password. The password is fixed to “746”. If write protection has been turned on, it has to be entered by <->, <+>...
  • Page 24 4.2.2.15 Setting of the tank shape and characteristic curve The transmitter allows selection of a tank shape according to VDI/VDE 3519 page 1 (DIN 28 011/28 013). Hereby, the volume is calculated from the product level (not interface) and displayed. Access: Setup ->...
  • Page 25 For calculation of the fill mass, the density (specific weight) of the medium has to be entered additionally. Access: Setup -> Tank -> Density 0…9999 kg/m³ Possible values: 4.2.2.16 Selection of the mounting direction The sensor can be mounted from top or bottom into the vessel. This com- mand turns the digital sup-plied values in a way that the level and interface always count from zero (bottom) upwards.
  • Page 26 4.2.2.17 Selection of the used magnet type The sensor functions with several float magnet types. For correct function, the type of the used magnet type has to be entered into the sensor. Due to the fact that a wrong magnet type affects measurement seriously, the customer should take extreme care when using this function.
  • Page 27 4.2.2.20 Setting of the display mode The display’s value can be set for the normal operation. Access: Setup -> Display -> Mode Possible settings are: Setting Description iToggle *) Toggles every 3 seconds between Level, Interface, Temp PCB, SNR, Percent PV, Current, absolute Filling volume, percentage Filling volume and filling mass.
