Scylar Model 5202S System Overview ISTEC’s BTU meters, also referred to as energy meters, are ideal for all sub-metering and performance verification applications. Several different types and models are available to fit almost any application, including hydronic heating and/or cooling, solar thermal, geothermal, water-source heat pump and co-generation. Meter data can be collected locally or remotely and easily exported into an Excel spreadsheet for trending and billing purposes.
ISTEC’s BTU (Energy) Meters measure the energy used or transferred in a liquid system. Utilizing precision matched temperature sensors providing excellent differential accuracy and in-line flow meters with a very wide turn-down, they provide the accurate data required to effectively trend energy usage and allocate cost. Energy is calculated by multiplying the temperature difference (∆T) between the supply and return lines by the volume of liquid. The result can be displayed in common units such as BTUs or kWhs.
|Scylar Model 5202S – this calculating unit can be used in conjunction with ISTEC’s 1800 or 1700 Series water meters. (more info)||4400 Series – a 3/4" self-contained energy meter with pulse output. Available in heating or heating/cooling models. Ideal for sub-metering energy usage in condos, apartments and commercial office space. With its EN 1434 (OIML) approval, it can be used for Solar Renewable Energy Certificates (SRECs). (more info)|
ALLOCATION METHOD BASED ON ENERGY METER READING AND SQUARE FOOTAGE OF APARTMENT
This sample allocation method is for six tenants and is based on Energy Meter Readings and Area of the tenant's apartment (base cost).
The apartments in this example have three different square foot areas. 50% of the total energy cost will be allocated based on the square foot area of each apartment and 50% will be allocated on the energy meter readings.
