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.
- Enhanced Accuracy in Turbulent Flows:
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.
- Versatility in Fluid Types:
TVT technology is versatile and suitable for a wide range of fluid
types, including liquids with varying viscosities and densities.
