Luminor LFM-0.75 Ultrasonic UV Flow Meter 3/4" NPT 0.1-30 GPM

Overview

The Luminor LFM-0.75 adds real-time flow measurement to compatible BLACKCOMB UV systems. During low-flow or no-flow conditions it signals the controller to reduce UV lamp output, helping reduce energy use, operating temperature and quartz-sleeve fouling.

Important Note

The module requires a compatible Luminor UV controller running firmware version 2.13 or newer and accepts +5VDC only. It must be installed on the inlet side of the UV chamber with enough straight inlet pipe and a continuously full pipe.

Benefits

Measures flow from 0.1 to 30 GPM
Supports automatic lamp-output reduction during low or no flow
Can reduce energy consumption and heat during periods without demand
Provides real-time flow feedback to a supported BLACKCOMB controller
