SE509 Ultrasonic Energy Meter
Clamp-on simple type ultrasonic energy meter.
Introduction
SE509-PT1000 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 resistancechange of the temperature change can be converted to known as thermal resistance sensors.
SE509-PT1000 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.
Main Features
Flo-Instruments SE509 ultrasonic flowmeter offers high-accurate, repeatable and stable flow measurement for liquids. It is made of strong metal case. Combined the outstanding performance transducer with high industrial grade material, it's ideal for pipes size from 1''(25mm) up to 80''(2000mm) in diameter. IP68 transducers that are easy to install requires this pipe not to be cut, thus reducing installation and labor costs. Clear and obvious interface makes it very convenient to operate.
Working Principle
Introduction to TVT
TVT(Transit-Time Vortex) technology represents a cutting-edge approach to ultrasonic flow measurement, combining the principles of transit-time ultrasonics with the capability to harness the vortex shedding phenomenon, delivering unparalleled accuracy and versatility in ultrasonic flow meters. This innovative integration technology enhances the accuracy, versatility, and performance of ultrasonic flow meters, making them well-suited for a wide range of applications across various industries and is a valuable solution for industries requiring precise flow measurements in varying flow conditions.
TVT technology excels in applications where fluid flow conditions vary between laminar and turbulent. The incorporation of vortex shedding data enhances accuracy in challenging flow environments.
TVT technology is versatile and suitable for a wide range of fluid types, including liquids with varying viscosities and densities.
