In Selection section you can select values to input. Provides flexibility to meet all applications The 212 is able to cross international boundaries in heat meter applications. Read on to learn how to apply the heat capacity formula correctly to obtain a valid result. Four operating modes are avail- able. Equation used in the calculator is:. Location: 1 x Feed Line and 1 x Return Line. When the push buttons are activated the display reacts immediately by calling other readings.
Pulse frequency 1 Hz 3 Hz Electrical isolation No No Max. Not selected values will be calculated. Calculator can be used for hot water boilers, water and air heat exchangers, hot water radiators, water chillers, air heaters and other heat power generation and consumption units. In addition to current temperatures for the energy calculation average temperatures on a yearly and monthly basis can also be displayed. The 212 is fully programmable and all set-up data and totals are stored in a non-volatile memory for a minimum of 10 years. K-factor Range: Programmable in the range 0. Heat energy calculator oiml r If this is the case, we recommend disabling these add-ons.
Inputs Flowmeter Type: Frequency or pulse between 0. Thermal energy and heat power calculator can be used for chilled water production flow rate calculation when heat power of refrigeration is known, or calculator can calculate hot air production if input heat power is known. Bus Address: Programmable for multiple instruments on the same bus. Pulse frequency 128 Hz 1 Hz 128 Hz Integration frequency 1 Hz 1 Hz 1 Hz Electrical isolation No No 2 kV Max. Thermal energy and heat power calculator can be used for calculation of thermal energy and heat power water production in boilers or thermal energy required for heating specified volume of water or some other fluid. This is the typical heat capacity of water. In Report section you have instant calculation report for input values.
The changeover times between peak and off-peak are fully programmable. You can also go to advanced mode to type the initial and final values of temperature manually. The pulse inputs are physically placed on the plug-in modules. Calculates the density and enthalpy of water The 212 Heat Meter measures the tem- perature in the feed and return lines and, from this, calculates the density and enthalpy of the water. Or, use calculator for heat exchanger and flow rate calculation or energy exchange quantity calculation in heat exchanger. If you want to cool down the sample, insert the subtracted energy as a negative value. You can select not to use this feature by selecting η in Omit section.
Typical values of specific heat You don't need to use the heat capacity calculator for the most common substances. The meter has no cutoff for low tem- perature and thus measures as low temperatures as 0. Physical Temperature Operating: 5 to 55°C. The lower push button is used to show secondary information on the selected primary reading. The voltage induced within the fluid is measured by two diametrically opposed internally mounted electrodes. Modes of Operation The 212 Heat Calculator is flexible enough to handle a wide range of appli- cations. The supply modules are exchangeable without breaking the verification seal.
In connection with energy and volume readings 7 digits and the units of measurement to match are used, whereas 8 digits are used when e. Mounting is either by a wall bracket or by panel mount. This specific heat calculator is a tool that determines the heat capacity of a heated or a cooled sample. The surveillance system consists of two water meters based on the ultrasonic principle, placed in flow and return pipe respectively, and of temperature sensors in both pipes. The consumers typically use the first primary readings in connection with self-reading for billing purposes. The info logger constantly monitors a number of key functions in the meter, such as error in measuring system, power failure, leak, burst, or mounting of sensor in wrong flow direction. Calculate thermal energy and heat power of water or air for heating and cooling or calculate flow rate of fluid that is heated or cooled with thermal energy and heat power calculator.
By also measuring the volume of water flowing in the system, the 212 will then compute the energy consumed. Operations optimisation In case of power failure data is backed up, thus securing billing of consump- tion data. Info code Description Response time 0 No irregularities - 1 Supply voltage has been cut off - 8 Temperature sensor T1 outside measuring range 1…10 min. . Function: High and low alarms individually programmable as unsigned values for flow rate, energy flow rate, feed temperature, return temperature or temperature difference. Datalogging flexibility The 212 Heat Calculator will store ener- gy totals by hour, day, week or month for up to 31 periods.
If the sample is cooled down, the difference will be negative, and if warmed up - positive. Frequency: 1 pulse every preset number of units of energy or volume total. For example, we can assume that we want to reduce the thermal energy of the sample by 63000 J. Wondering what the result actually means? Location: In either the return or feed lines. This means that Yandex will not be able to remember you in the en. Your browser may con contain add-ons that send automated requests to our search engine. You can select not to use this feature by selecting ρ in Omit section.
Try our to check how high you would raise the sample with this amount of energy. Important: Specifications are subject to change without notice. K ΔQ: Heat required for the temperature change, in J ΔT: Temperature change, in K m: Mass of the object, in kg ». All energy types are data logged and can be displayed dependent of configuration. For instance, you can check how much heat you need to bring a pot of water to boiling so that you can cook some pasta. Calculator is also suitable for inverse calculation of fuel flow rate for known heat power.
