Advantages of DS Type Heat Meter Sensors

High Accuracy

DS type heat meter sensors have a resistance of 1000 ohms at 0°C, providing high precision and consistency in temperature measurement.

Wide Temperature Range

These sensors can operate over a broad temperature range, making them suitable for various heating and cooling applications.

Long-term Stability

DS type heat meter sensors maintain their accuracy over extended periods, ensuring reliable performance and reducing the need for frequent recalibration.

Durability

With robust construction, DS type heat meter sensors can withstand harsh environmental conditions, enhancing the durability and longevity of heat meters.

Key Functions of DS Type Heat Meter Sensors

Accurate Temperature Measurement

The primary function of DS type heat meter sensors is to provide precise temperature readings. The DS type heat meter sensor, known for its high accuracy and stability, is often used in heat meters. These sensors can accurately measure temperatures over a wide range, ensuring reliable data for energy calculations.

Energy Calculation

The energy consumption in a heating or cooling system is calculated based on the temperature difference between the incoming and outgoing fluid. Accurate DS type heat meter sensors are essential for this calculation, as even minor deviations can lead to significant errors in energy measurement and billing.

System Efficiency Monitoring

By providing real-time temperature data, DS type heat meter sensors help in monitoring the efficiency of the heating or cooling system. They enable the detection of any anomalies or inefficiencies, allowing for timely maintenance and adjustments to optimize system performance.

Installation Precautions for DS Type Heat Meter Sensors

● In case of replacement, the old temperature probe and the old seal must first be removed from the installation location without leaving any residue.
● Seals and sealing surfaces must be clean and free of damage.
● Strip the new seal from the probe and insert it into the installation point.
● Push the process thread of the temperature probe with open locking screw (optional) onto the temperature probe sleeve as far as it will go.
● Screw in the process connection as far as it will go (tightening torque: Nm4) and tighten the locking screw (optional) (tightening torque: cNm4).
● At the end of each installation, a leak test must be carried out.
● The probe must be sealed according to DIN EN 1434, use existing sealing points.

FAQ

Q: What is a DS type heat meter sensor?

A: DS type heat meter sensors are devices used to measure the flow and temperature of heat media (water, steam, etc.) to calculate heat consumption. They are usually composed of flow sensors and temperature sensors, and are suitable for heat energy metering scenarios such as central heating and central air conditioning.

Q: What are the core components of DS type heat meter sensors?

A: Flow sensor: Commonly used ultrasonic or turbine principle to measure the flow rate of heat media.
Temperature sensor: Mostly Pt100 or Pt1000 thermal resistors to monitor the supply and return water temperatures.
Signal processing unit: Calculates the product of temperature difference and flow rate to obtain the heat value.

Q: What is the measurement principle of DS type heat meter sensor?

A: Ultrasonic type: The flow velocity is calculated by using the time difference or Doppler effect when ultrasonic waves propagate in the fluid.
Turbine type: The fluid drives the turbine to rotate, and the flow rate is measured by a speed sensor (such as magnetoelectric type).

Q: Why is Pt100 commonly used in DS type heat meter sensor?

A: The resistance value of Pt100 thermal resistor is 100Ω at 0℃, the temperature coefficient is stable (0.00385Ω/℃), the measurement accuracy is high (within ±0.5℃), and it is suitable for medium and low temperature (-200~850℃) thermal energy measurement scenarios.

Q: How to calibrate the DS type heat meter sensor?

A: Flow rate: Calibrate using a standard flow device (such as weighing method, volumetric method);
Temperature: Calibrate by comparing with a high-precision platinum resistor in a constant temperature bath;
The overall heat accuracy needs to be verified by a heat calibration device (temperature difference × flow comprehensive test).

Q: What are the protection level requirements for DS type heat meter sensors?

A: Outdoor installation must reach IP65 and above (water spray proof), humid environments must be waterproof and moisture-proof, and the sensor housing is mostly made of stainless steel or ABS engineering plastics.
