SE509 Ultrasonic Flow Meter
▍Introduction
SE509 ultrasonic energy meter, which is used for measuring individual energy consumption in any liquid heating/cooling systems. The meter is supplied complete with flowmeter and temperature sensor, which can makes the system real-time detect the temperature of supply and return pipe.
The temperature sensor is to use conversion element characteristics of electromagnetic parameters change with temperature, the temperature and temperature related parameters for testing device.The resistance-change of the temperature change can be converted to known as thermal resistance sensors.
SE509 Meter provides highly accurate thermal energy measurement in chilled water, hot water and condenser water systems based on signal inputs from two temperature sensors and ultrasonic flow meters.

▍Installation
|
V Method
|
The V method is considered as the standard method. It usually gives a more accurate reading and is used on pipe diameters ranging from 25mm to 400mm (1～16”)approximately. Also,it is convenient to use, but still requires proper installation of the transducer, contact on the pipe at the pipe's centerline and equal spacing on either side of the centerline. |
|
Z Method
|
The V method is considered as the standard method. It usually gives a more accurate reading and is used on pipe diameters ranging from 25mm to 400mm (1～16”)approximately. Also,it is convenient to use, but still requires proper installation of the transducer, contact on the pipe at the pipe's centerline and equal spacing on either side of the centerline. |
|
N Method
|
With the N method, the sound waves traverse the fluid twice and bounce three times off the pipe walls. It is suitable for small pipe diameter measurement. The measurement accuracy can be improved by extending the transit distance with the N method (uncommonly used). |
|
W Method
|
As with the N method, the measurement accuracy can also be improved by extending the transit distance with the W method. The sound wave traverses the fluid four times and bounces four times off the pipe walls. It is suitable for very small pipe(diameters less than 50mm,2") |
