The BTU meter RH33 is used in applications with liquid energy carriers.It calculates the thermal energy of water acc. to EN1434, glycol/water mixtures or other fluids such as thermal oils. Temperature sensor matching using calibrated temperature sensors is done in the device. Potential for cost savings can be shown by using the software available as an accessory. The device has a custody transfer approval and allows bi-directional measurement, e.g. charging/discharging of a heat accumulator.
