    Operating principle The VF04 2-wire guided microwave level transmitter uses the TDR (Time Domain Reflectometry) principle. The instrument sends low power nanosecond wide pulses along an electrically conductive rod, cable or coaxial probe with a known propagation speed (the speed of light). As the pulse reaches the surface of the medium or ...

    3.5 M AINTENANCE AND REPAIR VF04 does not require maintenance on a regular basis. In some very rare instances, however, the probe may need cleaning to remove deposited material. This must be carried out gently, without damaging the probe. Repairs during or after the warranty period are carried out exclusively at the Manufacturer. The equipment sent back for repair should be cleaned or disinfected by the User.

    Threaded process connections Nozzle height The simplest and most economical way is to mount the VF04 2-wire directly Do not fit a nozzle longer than its diameter, especially for single on the tank with the 1” (1½”) BSP or 1” (1½”) NPT threaded connection.

    Electrostatic discharge (E.S.D.) VF04 2-wire non-Ex and Ex instrument electronics are shielded up to 4 kV against E.S.D. Note: E.S.D. cannot be fully solved by the VF04 2-wire internal E.S.D. protection. It is the customer’s responsibility to avoid E.S.D. by grounding the tank, product and probe installation.

  • Page 32 Note: The level can effectively be measured between 200 mm or 8” and 5600 mm or 18½ ft. When the product level drops below the tip of the probe, the VF04 2-wire will indicate that there still remains 200 mm or 8”. Accordingly, the VF04 2-wire can only indicate a level between 200 mm or 8” and 5600 mm or 18½ ft, since it only measures along the probes.

  • Page 35: Programming With Vgf-Display Display Unit

    ROGRAMMING WITH DISPLAY UNIT The main parameters of the VF04 can be also set using the VGF-DISPLAY display unit. The default display shows the primary measured value (which the output current is calculated from). Besides the numerical display there is a bargraph on the right showing the value of the current output.

    If HART communication stops the COM LED turns off after 120 sec. When leaving the VF04 in (programming) menu after 30 minutes the instrument automatically returns to measuring mode. If VGF-DISPLAY is removed the instrument instantly returns to measuring mode.

    Level measurement: Level pulse amplitude and threshold After connection to a power supply, the VF04 2-wire will: 1. Measure reflection pulses in terms of voltage amplitude by cycling through a set of gains. 2. Identify the highest amplitude as being the product level.
  • Page 44 The level signal can be optimized by way of two factors: Amplification factor The amplitude of the signals is proportional to the dielectric constant  of the product. At low amplitudes the signal should be amplified. The amplification factor is dependent on the dielectric constant  and on the probe type.
