System-40 Series BTU Meters provide highly accurate thermal energy measurement in water and water/glycol heating and cooling systems. Each meter includes an integral inline flow sensor and a pair of precision matched temperature sensors. The compact design also features an easy to operate user interface and is available in several different configurations.
APPLICATIONS
Monitoring chilled water, hot water and condenser water in AHU and CRAC units for:
• Commercial office tenant billing
• Residential apartment and condominium tenant billing
Monitoring renewable energy resources for:
• Solar thermal applications
• Ground source heat pumps
• Geothermal heating systems
Reliable No-Moving-Parts Design
The System-40 utilizes direct path wetted ultrasonic transducers to measure flow. This no-moving-parts design optimizes signal strength and ensures long-term reliability.
Operates Over a Very Wide Flow Range
The built-in ultrasonic flow meter has a 500:1 turndown
Precision Matched Platinum RTD Temperature Sensors
1000 ohm sensors are matched to a differential uncertainty of better than ±0.18° F.
Auxiliary Pulse Inputs
The System-40 with BACnet® MS/TP or MODBUS® RTU can be ordered with three auxiliary pulse inputs for totalizing pulses from water, gas or electric meters. This simplifies network connectivity in the tenant space.
Simple Installation and Commissioning
Each meter is delivered fully programmed and ready for use upon delivery. Commissioning is done through the user interface/display without the need for special tools.
Detachable Calculator
The System-40 electronics enclosure is easily detached from the flow body to allow for remote wall mount installations using the 5’ cable provided with the meter.
C900.1 / EN1434 Compliant
The System-40 is designed to meet the requirements of C900.1 and EN1434
