Sika Durchflussanzeigen VA3K01 mit VMM Operating instructions

  • I have analyzed the user manual for SIKA's VA3K01 display unit and VMM flow sensor. The document includes connection details, programming steps, and specifications for both devices. I'm ready to answer your questions about connecting and using them to measure flow.
  • What is the measuring range of the VMM flow sensor?
    What is the pulse rate of the VMM flow sensor?
    What is the current output range of the VMM flow sensor?
    What is the frequency output range of the VMM flow sensor?

Connect display unit type “VA3K01” to flow sensor type “VMM”
and programming
Example flow sensor VMM32D1110KAMA20 with the
data:
• Measuring range: 0–10 m³/h
• Pulse rate: 1000 pulses/m³
• Current output: 4–20 mA
• Frequency output: 0–1 kHz
Terminal assignment and connection of VA3K01 and VMM:
Terminal assignment VMM:
4 = pulse output (passive) –
5 = pulse output (passive) +
6 = status output (passive) –
7 = status output (passive) +
8 = current output (active) –
9 = current output (active) +
Terminal assignment VA3K01:
1 = INP A (signal input A)
8 = 24V DC (sensor supply voltage)
9 = GND (sensor supply voltage)
Supply voltage VA3K01:
(see operating manual VA3K01, p. 21)
16 = 10…30 VDC (supply voltage)
17 = GND (supply voltage)
