Impulse Counter Wi‑Fi 12–24 V AC/DC IME S.p.A. LIW-01 (SPL10000026)

The IME S.p.A. LIW-01 impulse counter is a Wi‑Fi enabled device designed to read and transmit pulse signals from meters and sensors. Powered from 12–24 V AC or DC, the unit counts incoming impulses and sends the data over a wireless network for remote monitoring and logging. Its compact design and network connectivity make it suitable for installations where wireless pulse reporting and integration with building management or data-collection platforms are required.

Advantages

The LIW-01 supports both AC and DC supply within a 12–24 V range, providing installation flexibility in different electrical environments. Built-in Wi‑Fi transmission removes the need for wired communication lines and enables integration with cloud or local monitoring systems. The device provides accurate pulse counting for a variety of input sources, allowing centralized tracking of consumption or production data. Its simple electrical interface and compact form factor reduce installation time and space requirements.

Suitable for

• Remote reading of water, gas or heat meters equipped with pulse outputs
• Flow monitoring systems in industrial or commercial sites
• Energy monitoring and submetering applications
• Automation systems requiring wireless pulse inputs

Key specifications

• Power supply: 12–24 V AC or DC
• Connectivity: Wi‑Fi wireless transmission for pulse data
• Input type: Pulse signal counting from meters and sensors
• Mounting: Compact enclosure suitable for DIN-rail or panel installation (depending on installer preference)
• Data output: Periodic or on-demand transmission of counted impulses over wireless network

How to use

Connect the LIW-01 to a 12–24 V AC or DC supply according to the electrical installation norms and wire the pulse output of the meter or sensor to the device input following the manufacturer's wiring recommendations. Configure the unit to join a local Wi‑Fi network and set the destination for pulse data—either a cloud service, local server, or monitoring platform—using the device configuration interface. Once online, the counter will accumulate pulses and transmit readings according to the configured reporting interval or on request.

Usage recommendations

Install the device in a dry, electrically safe location with stable Wi‑Fi coverage. Verify compatibility of pulse signal voltage and contact type before connection. Use secure network settings and follow local regulations for electrical installations. For reliable long-term operation, periodically check signal reception and data transmission logs.
