ST502 Ultrasonic Energy Meter for Energy Audit and Building Applications HVAC Cooling Tower Data Center

ST502 Ultrasonic Energy Meter

Clamp-on type ultrasonic energy meters for flow and heat consumption measurement.

Introduction

ST502 is a high-accuracy ultrasonic flow meter with clamp-on transducers measuring big pipe diameter, which is built-in RTD module. When it is equipped with PT100 temperature sensor, ST502 can be upgraded into energy meter used for measuring individual energy consumption in any liquid heating/cooling systems. The meter is supplied complete with flowmeter and temperature sensor, making the system real-time detect the temperature of supply and return pipe.

The energy meter can be widely applied in various applications, like HVAC, cooling tower, data center, energy audit, and building(shipping mall, office, museum, hospital, school, subway etc.). Energy meter, also called thermal energy meter or heat meter, is used to accurately measure heat consumption in heating and cooling facilities so that the user can reach energy-saving and cost-saving.

Benefits

• Measures the actual flow and total energy consumption of various liquids
• No loss of process control, optimization of assets and efficiency, no downtime or expense from calibration
• Adaptive signal processing algorithms optimize performance, ensuring accurate measurements even in challenging flow conditions.
• Clear display interface and LCD display with alarm function, easy to operate and debug
• Utilize transit-time ultrasonic technology so as to realize bidirectional flow measurement by precisely measuring the time it takes for ultrasonic signals to travel upstream and downstream
• Leverage the data logging capabilities to analyze historical flow patterns to make system optimization.

ST502 is a brand-new high-end product that is made of aluminum alloy material and realizes CNC processing method. It adopts the industry-leading full-sealed iron-absorbing side-opening technology without any screw locking, and the tedious steps of screwing are reduced. Such a convenient design truly realizes "one-second opening".

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.

Flo-Instruments ST502 ultrasonic flowmeter offers high-accurate and repeatable flow measurement for liquids at an economical price. 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 200''(5000mm) in diameter. IP68 sensors that are easy to install requires this pipe not to be cut, thus reducing installation and labor costs. Simple interface makes it very convenient to operate.

ST502-PT100 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.

ST502-PT100 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.
