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.
