The ECO Series product is an advanced pulse amplifier. It is designed for flush-mount (1 or 2 channels) or M14x1.5 screw-in (1 channel) installation. It is powered by an adjustable DC voltage ranging from 12 to 28 V, with a current consumption of less than 25 mA.

The amplifier supports a wide frequency range from 1 to 5,000 Hz and is suitable for all ZHM, SRZ, and HM mechanical flow meters. It offers various output modes, including:

  • Frequency/Pulse (Push-Pull active, PNP, NPN)
  • Frequency/Pulse (NPN) + 4-20 mA passive
  • Frequency/Pulse (Push-Pull active, PNP, NPN) + 0-20 mA active
  • Frequency/Pulse (Push-Pull active, PNP, NPN) + 0-10 V active

The amplifier can be equipped with an LED indicator for status display.

Temperature measurement is accurate with a precision of ±1 °C ± 0.5%. It can operate within a wide ambient temperature range from -40 °C to +60 °C, and it offers three different temperature ranges for liquid temperature:

  • From -40 °C to +80 °C
  • Up to +120 °C
  • Up to +150 °C

The product is made of die-cast aluminum alloy 231 or stainless steel, providing IP65 protection for aluminum and IP68 protection for stainless steel with a closed electrical connection. The compact design is ideal for use with flow meters. The product can also be configured for use in explosive atmospheres.
