Summary As the meter to measure the consumption calorie within the fixed heating range, this meter can be installed in all the places such as district heating, central concentration apartments, longhouse, etc where the measurement of calorie is available. And this meter aims at managing the heating by family and inducing the energy saving, and restraining the unnecessary heating with settlement of heating unbalance and enabling the provider both provider and user to operate the reasonable heat management through levying calorie on the heating rate by converting calorie in the operation part and delivering it to the indication part after transforming the temperature difference and flow in supply part and return part within heating to the electric signal. Features The flow part and operation part are connected in the separate type, and this meter is superior in endurance and semi-permanent.The indication part using LCD decreases the consumption current and lengthens the life span of lithum battery installed inside the indication part.Since the warning is displayed on LCD in the failure of calorie meter, it is easy to judge whether or not the calorie meter is normal.The error is little and lithum battery is installed in the meter, an electric type. Accordingly the separate power is not required.
Dimensions
StructureThis meter is constituted of the flow part to measure heat medium passing through heating loader, thermostatic part to sense the temperature of supply and return part, operation part to convert the signal received from flow part and thermostatic part to calorie, and remote instruction part to instruct the operation contents by receiving the signal of operation part. Flow PartIn proportion to passing volume of heat medium flow, this part the rotation of impeller to the flow instruction part using the deceleration gear, and then delivers the electric signal to the operation part every fixed flow(unit pulse).Thermostatic PartSing the resistance bulb of PT550 of which the temperature coefficient is high and exact, this part inputs the temperature of heat medium flowed on the supply pipe and return pipe, and temperature signal detected in each temperature sensor to the operation part. Operation Part This part operates the used calorie by compensating the electric flow of unit pulse, and the temperature signal(temperature) detected in the temperature sensor of thermostatic part to the calorie conversion coefficient.
