Product Description

 

TOP LOADING ORIFICE CALIBRATORS  

TLOC2 is an advanced calibrator designed for calibrating precisely the blower flow of HVS & RDS of all standard manufacturers.  It is designed for ease of operation & attaches directly to the top of a standard filter holder suitable for 8” x 10” filter paper.  Based on EPA design, it basically consists of a base plate, which can be fixed to the filter holder.  In the center of this plate is a cylindrical assembly with a precision machined orifice on the top.  A pressure tap below the orifice is used to measure pressure across the orifice, which is a measure of flow.  This pressure is measured by a solid-state pressure sensor housed in the display unit.  The micro-controller measure this signal along with the signal from a temperature sensor, mounted in the cylinder and display digitally the flow of air passing through the calibrator.  The unit has a provision for showing the flow under operating conditions as well as flow corrected for STP conditions i.e. 250C & 760 mm Hg absolute pressure.

SALIENT FEATURES

 

  • Designed as per EPA specification
  • Multi-function electronic unit with Digital Display of Flow for STP & operating conditions
  • Display of Differential Pressure across orifice
  • Display of operating temperature
  • Precision Design with high accuracy
  • Light weight Electronic Module 
Model PSI-TLOC1 is a traditional low cost calibrator & has a base plate assembly with a precision SS Orifice.  Its uses a U-Tube Manometer for measurement of differential pressure across orifice.  The flow is determined from the calibration graph provided with the calibrator.
