System-30 BTU Meter

The System-30 provides highly accurate thermal energy measurement in chilled water, hot water and condenser water systems based on signal inputs from two integral, matched temperature sensors and an integral ONICON inline turbine meter. This compact system is designed to provide totalized energy for low rates from 0.8 to 38 gpm. The totalized output is available as a solid state dry contact closure. Each System-30 is factory calibrated and comes complete with all installation hardware.




Standard Features

Single Source Responsibility
One manufacturer responsible for the manufacture, compatibility of components, and calibration of the entire BTU measurement system. ONICON is committed to providing highly accurate and reliable systems which guarantee successful installations.

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 over the calibrated range.

Simple Installation and Commissioning
Factory programmed and ready to use upon delivery.

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

Highly Accurate Flow Meters
Built-in turbine flow meter is accurate to within ±0.5% at the calibrated flow rate and within ±2% of reading over an extended range (0.8 - 38 gpm). Each ONICON flow meter is calibrated against a primary volumetric standard directly traceable to NIST with calibration certification provided.

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

Typical Applications
Chilled water, hot water and condenser water systems for:

        • Commercial office tenant billing
        • Residential apartment and condominium tenant billing
