Cooling & Heating Energy Ultrasonic Flow Meter – EUF1568LH

Model: EUF1568LH

Hurricane EUF1568LH series flow meter is designed to measure both the cooling energy & heating energy. With the advanced digital technology and intelligent self-adjust sound technology, the flow meter with features of high reliable and low maintenance cost.


With 2 temperature sensor inputting, build-in heating/cooling energy calculator, it makes the EUF1568LH calculate the value of energy easily.


The EUF1568LH is suit for the measurements on concentration supply of cooling, heating energy; for buildings, stores and residential etc. The sensor can choose from clip-on type, plug-in, the tube-stages etc three installation way, according to the real application.


EUF1568LH is an Ultrasonic flowmeter which with advanced modular unibody design, independent menu operation, LCD backlit, product transmitter protection level IP65, sensor protection level is IP68, can be used in damp, such as for the use of harsh environment.


Can be used in various application with RS-485 communication interface, 4-20 mA current signal, Modbus, support product all-weather working.

Installation, choose points


It is very easy to install the ultrasonic flow meter. Choose one suitable checking point, set the pipe parameter on the flow meter, and fix the transducer on the pipe, and then the flowmeter works. Please take reference on the rules as below while installing.

Checking-point select

The installation of ultrasonic flow meter is the most simple and quick in all flow meter. Only choose one suitable checking point, input the pipe parameter to the flow meter and fix the transducer on the pipe then can make the measurement. Please take reference on the rules as below while installing.

Checking-point select principles
1.Get avoid from the position point 6 and 12 at o ‘clock direction to avoid signal attenuation due to the sediment at the bottom of the pipe or the bubble and cavitations.
2.Adequate consider the deposit condition within the pipe, try to choose the part without deposit for measurement. When completely meet the conditions, it need to take deposit into consideration as lining for better measurement accuracy.
