SYSTEM-10 BTU METER

The System-10-P1 BTU Meter provides highly accurate thermal energy measurement in chilled water, hot water and condenser water systems based on signal inputs from two matched temperature sensors (included) and any of ONICON’s insertion or inline flow meters (ordered separately). The System-10-P1 provides energy, flow and temperature data on a local alphanumeric display and to the network via the P1 (FLN) communications driver. An optional auxiliary input is also available to totalize pulses from another device and communicate the total directly to the network.

APPLICATIONS
Chilled water, hot water and condenser water systems for:

• Commercial office tenant billing

• Central plant monitoring

• University campus monitoring

• Institutional energy cost allocation

• Performance/efficiency evaluations

• Performance contracting energy monitoring

NIST Traceable Calibration with Certification
Complete system-wide calibration for the entire BTU measurement system for each specific application with certification of calibration.

Precision Solid State Temperature Sensors
Custom calibrated and matched to an accuracy better than ±0.15° F from 32-200° F.

Simple Installation and Commissioning
Factory programmed and ready to use upon delivery, all process data and programming functions are accessible via front panel display and keypad.

Easy-to-Operate User Interface
Menu driven display and membrane keypad make viewing data easy and simplifies field re-programming when necessary.

Network Compatible Serial Communications
Optional communications card provides complete energy, flow and temperature data through a single network connection. Available with LONWORKS®, MODBUS®, Johnson Controls-N2, Siemens-P1 and BACnet® interface cards.

Highly Accurate Flow Meters
Each System-10 BTU Meter works with ONICON’s insertion, inline, electromagnetic, clamp-on ultrasonic and vortex flow meters.

Installation Hardware Package
Thermowells and the associated installation hardware are provided along installation instructions to ensure error-free installation and accurate system performance.
