Ultrasonic Inline Flow Meters |
 |
Ultrasonic Inline Flow Meters are engineered to elevate water treatment and usage measurement. The ultrasonic inline flow meter module operates as a pulse generating device with corresponding K Factor for accurate flow measurement when connected to commonly used industry controls. Made in USA. |
| |
Features
• Real-time monitoring allows immediate detection of leaks and water usage irregularities,
enabling water conservation
• Innovative use of ultrasonic technology uses no moving parts within the water stream to
increase service life
• Stainless steel construction ensures durability & reliability even in the most demanding environments
• Familiar pulse output mode operation allows meter to be applied to wide variety of control devices
• Meter module can be updated or serviced without removing meter body from plumbing
|
• Accuracy over an extended period of time
• Less clogging, and less wear and tear
• Passivated surfaces and materials resist scaling
• Highly visible LED flow indicator
• Male threaded inlet adapter for direct mating to treatment control valve
• Boss provided on outlet for drilling/tapping 1/4 inch sample port |

During Operation
LED flashes as forward flow is sensed within meter. Flashing is proportional to the rate of flow sensed.
Higher flow rate generates higher frequency of flashing. |
