Wireless Transducer Reader

Many facilities have mandates to reduce energy use (e.g. 5% reduction from prior year). Most unfortunately do not have any baseline data from prior years to compare to, and must install instrumentation and record the necessary data. This can be an expensive and time consuming exercise to install new transducers, run wires, create drawings, connect I/O panels, and configure software.
Cypress Envirosystems’ Wireless Transducer Reader (WTR) is a fast and low-cost alternative to obtain baseline energy use characterization. When paired with non-invasive clamp-on current meters and clamp-on ultrasonic flow meters, the WTR can measure electrical consumption, and flow rate of chilled water or steam and transmit the data wirelessly. Installation typically takes minutes, and may be uninstalled and moved easily around a facility if needed.
  • Reads virtually any analog transducer or instrument with 4-20mA, 0-5V, 0-10V, or thermocouple output and transmits data wirelessly
  • Pager/cell notification of excursions
  • Compatible with flow meters, current meters, weigh scales, particle counters
  • Enables low cost energy audits, equipment health monitoring, predictive maintenance
  • Reduce labor, improve uptime, save energy
  • OPC and BACnet interfaces for integration with existing automation systems
  • Battery life of 3+ years at typical sample rates
  • IP65/NEMA 4 rated for outdoor use

The WTR is now available on GSA Schedule:

1. Orifice diameter should not be confused with pipe diameter. Consult the steam trap manufacturer if orifice size is not known.
2. Calculations are theoretical estimates and actual results will vary. Payback calculation includes avoided lost steam and inspection labor. Benefits from avoided damage resulting from blocked traps are not included in model. The formula used for steam loss in this model is: L=24.24*Pa*D2. Where L=pounds/hour, Pa=Pgauge + Patm , D=orifice diameter. http://www1.eere.energy.gov/manufacturing/tech_deployment/pdfs/steam_pressure_reduction.pdf
3. Actual WSTM installed cost will vary based on volume and integrator.
4. Refers to the manual inspections of steam traps that are currently being done at the facility. The frequency determines the potential avoided failure time when using the WSTM.
5. The frequency and cost of inspection determine the labor savings enabled by the WSTM.
6. The failure rate per year should be based on historical data from the facility. 15-20% failure rates per year are typical. In unmaintained facilities, the failure rate can be much higher: http://www1.eere.energy.gov/femp/pdfs/om_combustion.pdf
