Wireless Gauge Reader

Non-invasively retrofit analog pressure/temperature gauges for remote monitoring
Analog dial gauges which measure pressure, temperature and airflow are found in virtually every facility monitoring compressors, chillers, air handling units, coolant loops etc. In older buildings, gauges may be the only instrumentation available, and technicians are required to perform regular “rounds” with clipboard and pencil to log gauge data. It is a time consuming and error prone process.
Traditionally, replacing gauges with electronic transducers have been disruptive – requiring process shutdown, leak checks, drawings changes, and installation of cabling. A single transducer point can cost $4,000 to $6,000 installed.
Cypress Envirosystems’ patented Wireless Gauge Reader is a non-invasive device which simply clips-on to the front face of an existing gauge to capture and transmit the reading. It installs in minutes and does not require removal of the old gauges, breaking pressure seals, performing leak checks, running wires or interrupting the underlying process. It costs 70% less to install than a traditional transducer.
  • Non-invasive installation: no need to remove old gauges, break seals, or run wires
  • Reads analog gauges and transmits data wirelessly
  • Compatible with wide range of gauge styles and sizes, including Magnehelics
  • Pager/Cell notification of excursions
  • 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

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.
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:
