Mechanical Heat Meter

The mechanical calorimeter determines the velocity of the fluid by passing it over a tribune; It has a measurement and calculation system that calculates the volume of the fluid depending on the turbine speed.

TECHNICAL INFORMATION

    MECHANICAL HEAT METER ABOUT

  • Mechanical heat meter Compact meter type and hybrid device according to EN 1434 consists of 3 main units with flow sensor measuring calorimeters, pair of temperature sensors and calculator. After these parts have been assembled and calibrated at the factory, they cannot be taken apart, added or changed unless approved by the authorized service or an accredited laboratory.

  • Water Volume has a measurement and calculation system that calculates the velocity of the fluid depending on the velocity of the trine by passing the fluid over a tribune based on the transit time method, and the accuracy of this method has been proven. 'Transmission time downstream' to the transmission time of sound pulses sent downstream, 'transmission time downstream' to the transmission time of sound pulses 'upstream' The difference between the 'transition time in the flow direction' and the 'Transition time in the opposite flow direction' is an indication of the flow rate of the fluid.

    It provides ease of use as it is compatible with horizontal, vertical, inlet and return mounting.

Flow Sensor.

  • If the flow sensor, calculator or sensor is disconnected and the seals are broken, the meter is no longer valid for billing purposes. Also, the factory warranty is no longer valid.

  • Mechanical Measuring Method Used in Mechanical Heat meter Basically, the compatibility of the Mechanical Sensor and all units ensures exceptionally high measurement accuracy and reliability.

  • The LCD screen structure of mechanical heat meters is designed with high contrast, transflective and operating temperature. Therefore, the accumulated heat energy and/or cooling energy can be displayed in kWh, MWh or GJ, all in eight digits, including fraction points and unit of measurement.

  • Other reading options are: accumulated water consumption, operating hours counter, current temperature measurements, current flow and power readings. Also, Mechanical calorimeter logs, target day data, error hour counter, max. flow, max. power, info code and current date/time.

  • ER14505 and ER18505 battery options can be used in mechanical calorimeters. The ER14505 battery has a capacity of 2600mAh and the heat meter life is 5-6 years. The ER18505 battery has a capacity of 4000mAh and a heat meter life of 10-12 years. these are normal operating mode values.

  • Sealing plan and locking system of mechanical heat meter; The sensor and calculator seal during fabrication on the brass body, and the temperature sensor seals during assembly.
    IMPORTANT: If the seals are broken, the meter is no longer eligible for billing. Therefore, the court can only be opened by an authorized laboratory with the authority to re-verify the meter after it has been approved.

PM01 Ultrasonic Heat Meter

PM01 is a combined type measuring instrument based on the ultrasonic measuring principle. It is a measuring device that can be used in hybrid system-based heating and cooling systems. It uses water as the energy carrier and precisely calculates the flow rate of water by sending sound waves in the direction of the flow and against the direction of the water flow.

TECHNICAL INFORMATION

    PM01 ULTRASONİC HEAT METER ABOUT

  • According to EN 1434, the compact meter type and hybrid device consists of 3 main units with a flow sensor measuring heat meters, a pair of temperature sensors and a calculator. After these parts are assembled and calibrated at the factory, they cannot be taken apart, added or changed unless approved by the authorized service or an accredited laboratory.

  • Water Volume is measured using a two-way ultrasonic technique based on the transit time method and the accuracy principle of this method has been proven. 'Transmission time downstream' to the transmission time of sound pulses sent downstream, 'transmission time downstream' to the transmission time of sound pulses in the opposite direction of flow 'opposite flow'. The difference between 'transmission time' in downstream and 'transition time' in downstream direction. It is an indicator of the flow rate of the liquid.

  • These PT1000 platinum temperature measurement sensor pairs are produced in accordance with the EN 60751 standard and are mounted at the pipe inlet and outlet. In the production phase where the flow sensor is located, the first sensor is mounted and sealed, the second sensor is mounted on the ball valve by the service.

    It provides ease of use as it is compatible with horizontal, vertical, inlet and return mounting.

Compatible with dry and wet type temperature sensors.

  • If the flow sensor, calculator, or sensor pair is disconnected and the seals are broken, the meter is no longer valid for billing purposes. Also, the factory warranty is no longer valid.

  • Ultrasonic Measurement Method Used in PM01 Ultrasonic Heat meter Basically, Ultrasonic Sensor pair Temperature sensors and microprocessor technology inside the computing unit and the compatibility of all units with each other provide exceptionally high measurement accuracy and reliability.

  • The LCD screen structure of the heat meter is designed with high contrast, transflective and wide screen, operating temperature and optional backlight option. Therefore, the accumulated heat energy and/or cooling energy can be displayed in kWh, MWh or GJ, all in eight digits, including fraction points and unit of measurement.

  • Other reading options are: accumulated water consumption, operating hours counter, current temperature measurements, current flow and power readings. In addition, PM01 logs display target day data, error hour counter, max. flow, max. power, info code and current date/time.

  • ER14505 and ER18505 battery options can be used in heat meters. The ER14505 battery has a capacity of 2600mAh and the heat meter life is 5-6 years. The ER18505 battery has a capacity of 4000mAh and a heat meter life of 10-12 years. these are normal operating mode values.
