LDB220 electromagnetic cooling Heat meter energy meter heat meter split type energy meter PT1000 Brooks

LDB220 electromagnetic cooling Heat meter is a kind of measuring instrument to measure the heat released by the cooling and hot fluid in the heat transfer system. It uses a high-precision and highly reliable electromagnetic flow meter for flow measurement, and uses a high-precision and highly stable PT1000 platinum resistor for temperature measurement. The special high-temperature resistant material lining does not deform at 260 ℃, making the heat meter have excellent measurement performance. It can be widely used for measuring the cooling and heating capacity of residential areas, office buildings, and enterprises and institutions, such as centralized heating, heating, and air conditioning.
2、 Features:
Using a 16 bit microcontroller for data calculation, platinum resistance for temperature measurement, and electromagnetic flow meter for flow measurement, the measurement accuracy is high
Stable and reliable application, with excellent performance.
The measurement accuracy is not affected by changes in parameters such as viscosity, density, pressure, conductivity, and fluid distribution of the cooling and hot fluids.
There are no resistance components, no pressure loss, and no adverse water quality effects inside the measuring tube.
The measurement flow range is wide, and the flow rate can be set arbitrarily within the range of 1m/s to 10m/s.
The large screen LCD backlight source is fully displayed in Chinese, allowing clear readings in both strong and dark conditions.
Display data such as accumulated heat, accumulated flow rate, instantaneous heat, instantaneous flow rate, inlet temperature, outlet temperature, and temperature difference simultaneously
Capable of querying and displaying parameters such as flow rate and power outage records.
Adopting the enthalpy correction method with random temperature changes to ensure accurate measurement at different water temperatures.
　　

It has a unified DC signal and frequency signal output function, and this function can be switched between heat and flow parameters.
Equipped with batch processing (quantitative output), equivalent pulse output, and keyed direct reset function.
Equipped with RS-485 (RS-232, M-BUS, and HART optional) digital communication output, convenient for remote communication.
