Hard Water Monitoring Flow Meter (with Alarm Buzzer) Model Number: M51TW-7821M
To prevent scaling in cooling towers and heat pipes, we monitor the corrosion of pipes caused by concentrated residual chlorine and calcium carbonate.
To prevent scaling in cooling towers and heat pipes, we monitor the corrosion of pipes caused by concentrated residual chlorine and calcium carbonate. This single unit measures the increase in concentrated chlorine levels via conductivity, the rise in calcium carbonate hardness through TDS, and the timing for membrane replacement through cumulative flow, notifying users with a buzzer alarm. ● Selectable display for conductivity (µS/cm) and TDS (ppm) ● Warning with buzzer sound and LED flashing during water quality deterioration ● Cumulative flow 100–999900 L ● Instantaneous flow 3.0–100 L/min ● Connection port G1”
basic information
■Surface Panel You can switch displays and toggle between manual and auto modes using only the button operations on the surface panel. ■Manual Mode: It measures and displays the current water flow rate and water quality. ■Auto Mode: It automatically determines whether the average values of conductivity and TDS exceed the set upper limit alarm for every 40 liters of water flow. Even during power outages or battery replacements, the alarm settings and cumulative flow values are automatically saved in internal memory. ■Power Supply Please connect to DC5V (0.5A) or insert three AA alkaline batteries into the unit to power it on. When using batteries, the remaining power will be displayed.
