Flexible pulse counting, engineered for the field.

LiquiCount LC1

Information

The LiquiCount LC1 is a dual-channel pulse counter designed for integration into anti-ice and de-ice fluid handling systems used by air-side ground support vehicles. The LC1 has been engineered to install easily, configure quickly and provide straightforward day-to-day operation.

The LC1 accepts pulse inputs from proximity switches, turbine meters, or digitiser outputs and other pulse generated sensors. All inputs and outputs are electrically isolated from the onboard controller for safety and reliability. These pulses are converted into measurable units, which can be displayed in either litres (L) or gallons (G). Each channel’s K-factor is fully adjustable, allowing calibration to match the specific characteristics of your sensors.

A bright, backlit LCD shows the total count volume measured during the current job or session. Values can be reset at any time to start a new measurement cycle. In many applications, the LC1 also provides digital outputs—grounding pulses that correspond to defined units—making it compatible with external systems such as printers, loggers, or PLCs.

Advanced configuration is accessed via a secure, engineer-only menu, protected by a keycode. Within this menu, K-factors can be tuned and digital outputs tested by triggering sample pulses without dispensing fluid, making it ideal for setup and verification. The displayed labels on the standard display screen can be changed to display any word that uses the Roman alphabet and numbers 0 to 9. There are 9 characters available per channel.

The LC1 operates on standard 12 to 24V DC systems and connects directly to modern two or three-wire PNP proximity switches without requiring external resistor networks.

For air-side ground support operations, the LiquiCount LC1 delivers the precision, flexibility and reliability needed to monitor anti-ice and de-ice fluid use.
