S418-V Vacuum Flow Meter

S418-V Inline Vacuum Flow Meter with integral data logger

S418-V is the latest model based on the S418 generation of inline thermal mass flow meters and is specifically designed for vacuum flow applications. S418-V has an integral display, Bluetooth interface and communication options for analogue 4-20mA plus pulse, digital Modbus/RTU or digital M-Bus.

The S418-V Vacuum Flow Meter has the same size range of DN8 to DN25 as S418/S415, internal absolute pressure sensor and an integral 8 million sample data logger with USB interface. The integral data logger and high accuracy make it a perfect standalone instrument for consumption analysis or performance verification.

  • DN8, DN15, DN20 or DN25 inline designs
  • Vacuum/Pressure range 0.01 to 1.6bar(a)
  • Output 4-20mA + pulse, Modbus/RTU or M-BUS
  • Accuracy 1.5% of reading
  • Bluetooth interface for remote reading via SUTO Android App
  • Integral absolute pressure sensor

The integral flow conditioner means there is no need for extended straight lengths of pipe either side of the unit, allowing installation in restricted spaces without affecting the measurement accuracy. The S418-V vacuum flow meter replaces the earlier S419 model.
