GUF140
PRODUCT DESCRIPTION
FEATURES
Insertion Ultrasonic Water Meter
GUF140 series Insertion ultrasonic water meter is a new-style
water meter specifically designed for agricultural
irrigation,garden management and water resource supervision.
Advantage of this water meter include low cost,high
accuracy,low power consumption,stability and reliability.1 inch
thickness of the meter helps to save the installation space,and
all parts achieve to IP68 enable the water meter work in any
severe environment.Due to the unique design structure,there
will be no pressure loss and different water medium will have no
influence on measurement. This ultrasonic water meter will be a
major breakthrough for water measurement in agricultural
irrigation.
1.Characteristics
Protection Class IP68
Whole machine waterproof :the seal property of whole machine achieve to IP68
Parts waterproof : each part achieve to IP68 separately ,ensure long term work even if the meter get into the water.
Built-in Quantitative Controllers Built-in Time Accumulator
Automatically start the controller at the set time, achieve to supply water automatically ,regularly and quantitatively
Time-sharing flow accumulation with in the set period of time ,to achieve gradient rate..
Ultrasonic measurement ,no Rotation,no worn parts
Ensure long-term high measuring accuracy .
Apply to varieties of water quality, including the water contain gravel and weeds.
Ultra-thin design
1 inch thickness of the meter helps to save installation space
Made of nylon ,high strength and corrosionResistance ,very low cost.
No pressure loss.
