Quick Brief

Place of Origin: Shanghai China (Mainland) Brand Name: DYNAMETERS Model Number: DMTFW Accuracy: ±1.0% Certificate: CE certificate Sensitivity: lowest flow rate 0.003m/s Protection Class: IP68 Ambient temperature limit: 0â„ƒ-65â„ƒ(for meter) Repeatability: Better than 0.2%

Specifications and Product Details:

DMTFW Series Ultrasonic Water Meter is a battery-powered transit-time flow meter utilizing advanced digital processing technology. It conforms to EN1434 Standard. The meters contain no moving parts and don’t need any external power, with advantages of ultra-low power consumption, high accuracy and reliability. The meters are designed for easy installation. Commonly, it is unnecessary for customer to set any parameters in the application field. The meters have the same conduit length with industrial mechanical water meter but can be used just as conveniently as mechanical water meters.

Features

1. Integral transmitter suitable for harsh environments.

2. Low maintenance no moving parts or flow obstructions translates into long-term stability.

3. Very low minimum measurable flow velocity (0.003m/s).

4.Self-adjusting transducer receiving circuit continually adapts for changing pipe parameters such as scaling or corrosion.

Applications :

1,Process control and instrumentation.

2,Substituting mechanical flow meters with high measuring reliability.

3,Technological measurements of instantaneous flow rate and consumption in water-supply networks.
