New Range of MID & RHI Approved Heat Flow Meters

By | December 15, 2016

The new Qalcosonic heat meter is MID Class 2 Approved for RHI and billing purposes for both heating and cooling applications. Meter sizes from DN15 to DN50 with BSP threaded and flanged connections, Qp values range from 0.6 to 15 m3/hr with R100 dynamic range as standard and R250 as an option covering a wide range of energy metering applications. Using ultrasonic technology means the meter has no mechanical moving parts, prolonging the life of the meter and ensuring long term accuracy.

The meter benefits from pulse outputs and a range of optional communication modules; including MBus, Modbus, LON and RF868 (Wireless MBus) making it ideal for AMR applications and linking with existing management systems. The Qalcosonic offers an IP67 rated protection on the flow sensor, which is standard when purchased with the cooling application option and also with Glycol applications.

The Qalcosonic stores the energy readings for both heating and cooling in separate displays, automatically changing over when the temperatures change. Along with the energy readings the meter also logs hourly, daily and monthly values useful for monthly billing and monitoring of historical data.

As standard the meter is battery powered with a 3.6V lithium battery giving a life greater than 12 years meaning little maintenance is required. There are also options for power modules for 12-42 V DC or 12 – 36 V AC using the battery power as a back-up.

Qalcosonic heat meters offer a choice of mounting for the calculator display. It can be mounted on the flow sensor, but where access to the meter is difficult the display can simply be unclipped and mounted on a wall, DIN rail or on a panel. 1.5m of cable from the flow sensor and temperature sensors is standard for the DN15 and DN20 sizes and 3m for the larger models with an option for up to 5m cable.

Horizontal and vertical installations are possible and no requirements for straight runs before or after the meter. Direct immersion pocket sensors are available for all sizes within the Qalcosonic range and for the smaller 15-20mm models one of the temperature sensors is mounted in the meter body, removing a portion of installation cost. The Qalcosonic heat meter is available from Bell Flow Systems, for more information please contact us on 0800 027 7786 or email
