Specification :

Series DMTFW ultrasonic water meters utilizes newest digital transit-time processing technology, with compact shape featuring longevity, good stability and high accuracy for all-electronic industrial environment. The meters contain no moving parts and don’ t need any external power, with the character of low power consumption. The meters are designed for easy installation. Even users don’ t need to set parameters. The meters have the same dimensions with industrial water meter but can be used just as conveniently as normal water meters.
Features
Æ With compact, solid shape, suitable for bad environment conditions.
Æ No moving parts, no pressure loss or abrasion.
Æ Low start-up flow rate minimum measurable flow velocity 0.003m/ s long-term stability.
Æ Self-adapting ultrasonic receiving circuit, can work normally and stably even when pipe is with scaling or corrosion.
Æ Quick transient response, can trace the flow rate change within seconds ( superior to electromagnetic flow meters) .
Æ With Infrared meter reading function.
Æ Battery power supply can work constantly for 6 years.
Æ Unique housing design, can work underwater.
Æ Flange is made by mold to remove possibility of leakage.
Æ With self-diagnosing function and fault indicator.
Main advantages:
Æ High measurements precision
Æ Long-term stability over a wide range of measured values
Æ High operational reliability and minimum maintenance requirements ( maintenance-free meters)
Æ Compared to mechanical meters, very low hydraulic losses
Æ Easy data reading, storage and evaluation/ processing
Æ Identification of leaks in water distribution systems
Æ Installation at locations here no external power sources are available
Æ Measured data transfer to remote control stations
Applications
Æ Process control and instrumentation.
Æ Substituting mechanical flow meters with high measuring reliability.
Æ Technological measurements of instantaneous flow rate and consumption in water-supply networks.
