Product Description

STACK & DUCT VELOCITY INSTRUMENTS

 SALIENT FEATURES

 

  • Microprocessor based electronics
  • Digital display of various parameters
  • Fast, reliable and accurate measurements
  • Battery powered operation
  • Compact, light weight, portable construction

 

Model PEM-SVM 1 is an On-line Stack & Duct Velocity Meter which provides digital display of linear velocity in ducts or stacks. It employs the methodology suggested by EPA / ISS for measurement of velocity in stacks. It computes the velocity at the point of location from the measured parameters, which include differential pressure across an  ‘S’ type Pitot tube, stack gas temperature and stack gas pressure. When measurements at multiple traverse points are taken, it automatically computes the average velocity and volumetric discharge of gas.  The system also has user program averaging for fluctuating velocities. The data can be transferred to a PC through the RS-232 serial port.

PEM-SVM 1 comprises a control module with sensors for measuring pitot ‘DP’ stack gas pressure and duct / stack gas temperature. The control module housing the electronics with solid-state pressure sensor is provided in an elegant cabinet with ABS casing

Model PEM-HVK 1 is a simple instrument, which facilitates accurate and precise measurement and display of Duct or stack temperature and differential pressure of a Pitot tube installed in a stack. It includes an electronic stop-watch for timed measurements of the parameters.

 PEM-HVK 1 comes in an cabinet made of ABS plastic with handle and houses the solid state pressure sensor and necessary electronics for signal processing and display.
