AFLSS-27 wireless submersible liquid level transmitter is a high-precision, low-power wireless liquid level detection instrument. It consists of a submersible liquid level sensor, a signal processing circuit, a communication module and a power module; it is powered by a large-capacity high-energy lithium battery and transmits data via radio frequency. It is easy to install and use, does not require on-site wiring, and eliminates the trouble of wiring bridges for conventional instruments, saving manpower and construction costs. It is especially suitable for application sites where wiring is not suitable and power cannot be supplied. It is an ideal upgrade product for traditional liquid level transmitters.
