Ener Ray Series | ultrasonic thermal energy flow meter | South Korea
This item sale 41 countsEnerRay is an ultrasonic heat meter specially designed for heating, cooling or combined heating/cooling in local and central heating systems.
EnerRay consists of an ultrasonic flow sensor;
calculator with built-in hardware and software for measuring flow, temperature and energy consumption;
Temperature sensor.
The principle of measurement
| EnerRay flow unit and temperature sensor. The flow measurement method uses an advanced method |
| differences in the propagation times of the ultrasonic wave. The ultrasonic wave propagation time difference method uses |
| the principle according to which the transmission rate and direction of the ultrasonic pulse change depending on the velocity of the liquid. In each position, the flow rate |
| it is based on the principle that the time when the ultrasonic pulse is transmitted in the direction of the fluid flow is faster than the time when it is transmitted in the opposite direction |
Features
| A short straight pipe is required at the rear end of the bend (5D/2D) |
| ☞ Using a circuit that is fully field-tested using advanced noise reduction technology |
| ☞ The design of the STS316L sensor housing completely covers the ultrasonic generator, providing full protection from external shocks. |
| ☞ There are no moving parts inside |
| ☞ There is no pressure loss, and the flow measurement range is wide. |
