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：
◆With compact, solid shape, suitable for bad environment conditions.
◆No moving parts, no pressure loss or abrasion.
◆Low start-up flow rate,minimum measurable flow velocity 0.003m/s，long-term stability.
◆Self-adapting ultrasonic receiving circuit, can work normally and stably even when pipe is with scaling or corrosion.
◆Quick transient response, can trace the flow rate change within seconds (superior to electromagnetic flow meters).
◆With Infrared meter reading function.
◆Battery power supply,can work constantly for 6 years.
◆Unique housing design, can work underwater.
◆Flange is made by mold to remove possibility of leakage.
◆With self-diagnosing function and fault indicator.
Main advantages:
◆High measurements precision
◆Long-term stability over a wide range of measured values
◆High operational reliability and minimum maintenance requirements (maintenance-free meters)
◆Compared to mechanical meters, very low hydraulic losses
◆Easy data reading, storage and evaluation/processing
◆Identification of leaks in water distribution systems
◆Installation at locations here no external power sources are available
◆Measured data transfer to remote control stations
Applications:
◆Process control and instrumentation.
◆Substituting mechanical flow meters with high measuring reliability.
◆Technological measurements of instantaneous flow rate and consumption in water-supply networks.
