Ultrasonic flow transducer Landis+Gyr Ultraheat-2WR7 DN65

The ultrasonic flow meter ULTRAHEAT 2WR7 is intended for use as a flow sensor for calculators when accounting for heat or cold consumption. The readings of the flowmeter itself can, if necessary, be taken through the optoport.

The flow meter consists of a flow sensor (all-metal version) and an attached electronic module. These two components are rigidly connected to each other by a cable.

Characteristics:

• Working environment: cold and hot water (not applicable for glycol mixtures)
• Accuracy class (according to DSTU 3339-97): 2
• Protection class: IP54 (IP65 - option)
• Nominal diameters, mm: DN15-DN100
• Nominal flow range Qn, m³/h: 0.6…60
• Minimum flow, Qmin: 0.01*Qn
• Maximum flow, Qmax: 2*Qn
• Maximum medium temperature: 150 °C
• Power supply: 3.6 V lithium battery with a service life of 5 years (standard), 9 years (option)
• Output of accumulated information: via optical interface and via pulse transmitter
• Pulse output cable length: 2 m (can be extended up to 100 m)
• Pulse Output Pulse Width: 10m/s

The main advantages of the flowmeter:

• high accuracy and stability of flow measurement for a long time;
• wide range of flow measurements (1 - 200% of Qn);
• the flowmeter is made of a special alloy resistant to chlorinated water;
• the working part of the flowmeter is made entirely of metal and does not contain rotating parts subject to wear;
• insensitive to contamination due to automatic correction (amplification) of the ultrasonic signal;
• autonomous power supply from a lithium battery 3.6 V;
• the possibility of installing the flowmeter in horizontal, vertical and inclined pipelines;
• the design of the flowmeter does not require the installation of straight (calming) sections;
• archiving of monthly values of instantaneous volume, idle time and maximum consumption within 36 months;
• output of the accumulated information through the optical interface to a computer using the PappaWin light program and by means of a pulse transmitter.
