Leak Detection Method:
|
|
|
| |
Your choices are...
|
|
|
| |
Electrical Conductivity or Resistance
|
|
Device uses a low-voltage power source applied across separate electrodes. A conductive liquid contacting both probes completes a conductive circuit.
|
| |
Electrochemical Sensor
|
|
Responds to the presence or concentration of liquid chemicals. A selective chemical sensor. The output is presented as an amperometric, conductometric or potentiometric electrical signal.
|
| |
Mass Balance (Flow Metering)
|
|
Mass balance leak detection is based on the difference between inflow and outflow meters.
|
| |
Mechanical Float Switch (Relay Contact)
|
|
Devices use sealed reed switches in a stem with a permanent magnet installed in the float. As the float rises or falls (a level sensor), a switch is activated.
|
| |
Mechanical Line Leak Detector
|
|
Pressure sensing, piston operated valve or pressure vacuum switch indicates leakage in pressurized piping systems. For application wherever there is need to detect a loss of pressure in a liquid or fluid distribution line.
|
| |
Optical Leak Detector
|
|
Based on the absorption and collection of electromagnetic radiation. Device uses optic sensors and principle of optical refraction to detect presence or absence of fluid. Typically LEDs are utilized as the source of light.
|
| |
Positive Pressure or Vacuum Sensor
|
|
Detects pressure change in interstitial space of double-walled tanks.
|
| |
Ultrasonic Leak Detector
|
|
Based on mass and/or microviscosity alterations of acoustic wave propagation. Detects the ultrasonic noise created by gas moving through a small orifice; or recognizes the attenuation and dielectric properties of the liquid or air present (piezoelectric SAW devices).
