Metron MKLET Heat Meters totalise the consumption of energy in LTHW systems where water is the heating medium. A Metron heat meter consists of an energy Integrator , a flow sensor, flow/return sensors and immersion pockets. The calibrated sensors (PT500) determine the flw and return temperatures, while the flw sensor registers water volume, this data is calculated into Kwh consumption by the energy integrator. The integrator unit has a pulse output as standard, optional interfaces available include Mbus, Lonworks, RS232 and RS485. Manufactured from high quality MID approved components, providing high accuracy and long service life.
