 The meter operates with ultrasonic flowmeter transducers in combination with |
|
|
| temperature sensors for measuring supply water flowrate and the temperature |
|
|
| difference between supply water and return water, and then measure and display |
|
|
| the heat quality either released or absorbed by the water flowing through an heat |
|
|
| exchanger. It is specifically designed for the heating pipeline work of buildings. As |
|
|
| the meter works with ultrasonic flow measurement technology, it can be mounted |
|
|
| at any angles and remain unaffected in the pressure of magnetic interference. The |
|
|
| meter has no mechanical moving parts and is robust and long in service life, req- |
|
|
| uiring minimal service work. The meter is highly adaptable to water with a high |
|
|
| content of impurities. It is suitable for use in heating system of buildings, district |
|
|
| heating substations, heat-exchange substations, combined heat and power stations |
|
|
| and centralized heating or air conditioning system. |
|
| The meter falls into 2 major categories: one is the CRL-G-D building-use ultrasonic |
|
| heat meter and the other is the CRL-G-D (L) building-use ultrasonic heat (cold) meter. |
