Description
LR8512 Pulse Logger for Wireless Flow and Speed Measurement
The Hioki LR8512 Wireless Pulse Logger is engineered for professionals who require accurate, flexible, and safe measurement of pulse signals. Using Bluetooth® wireless technology, it transmits data to tablets or PCs for real-time monitoring and analysis. Data is automatically merged into a single file, allowing seamless review of trends and waveforms in the field.
Compact Design and Flexible Installation
With its pocket-sized 2-channel design, the LR8512 fits into tight spaces, including switchboards, control panels, or other hard-to-reach locations. Optional magnetic straps allow for wall or equipment mounting, providing installation flexibility. Wireless data collection eliminates the need to feed wiring through panels, ensuring safety and convenience during measurements.
Wide Application Across Industries
The LR8512 is perfect for monitoring flow rates in air conditioning systems, cogeneration units, and liquid distribution (water, gas, petroleum). It is also suitable for automotive testing, including vehicle speed monitoring, and other applications requiring pulse totalization or RPM measurements.
Reliable Data Storage and Long Battery Life
The LR8512 can store up to 500,000 data points per channel, supporting long-term monitoring. Powered by two AA batteries, it can operate for up to 14 days at a 1-second recording interval with Bluetooth active. For extended measurements, the device can use an AC adapter or external 5–13.5 V power supply. A power-saving function activates Bluetooth only during predefined intervals, maximizing battery efficiency.
