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.<\/p>\n
APPLICATIONS<\/strong> <\/p>\n 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.<\/p>\n The built-in ultrasonic flow meter has a 500:1 turndown<\/p>\n 1000 ohm sensors are matched to a differential uncertainty of better than \u00b10.18\u00b0 F.<\/p>\n The System-40 with BACnet\u00ae MS\/TP or MODBUS\u00ae 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.<\/p>\n 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.<\/p>\n The System-40 electronics enclosure is easily detached from the flow body to allow for remote wall mount installations using the 5\u2019 cable provided with the meter.<\/p>\n The System-40 is designed to meet the requirements of C900.1 and EN1434<\/p>\n","protected":false},"excerpt":{"rendered":" The System-40 BTU Measurement System provides highly accurate thermal energy measurement in chilled water, hot water or condenser water systems. It is provided as a complete meter and includes a matched pair of platinum RTD temperature sensors and an integral inline ultrasonic flow sensor. It is available for use in \u00bd\u201d through 2\u00bd\u201d piping systems with flow rates ranging from 0.03 to 250 GPM.<\/p>\n The native BACnet\u00ae MS\/TP and MODBUS\u00ae RTU versions of the meter communicate energy, flow and temperature data directly to the network. Three auxiliary terminals can be configured at the factory to provide pulse outputs, inputs, a combination of the two, or even a single analog output.<\/p>\n Pulse outputs provide volume or energy totalization to the BMS. Pulse inputs can bring in totalization pulses from local meters such as water, natural gas, or electric meters. Pulse input totals are accumulated in the internal registers and then transmitted to the RS-485 network. These totals are also available on the built-in display.<\/p>\n Analog outputs can be programmed to provide energy rate, volume rate, or temperature data to the BMS via a 4-20 mA \/ 0-10V \/ 0-5V signal.<\/p>\n Applications<\/strong>
