Leak Detection Method
   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). 
   Other       Other unlisted or proprietary leak detection method. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Specific Detectable Liquid Types
   Specific Detectable Liquid Types       
   Your choices are...         
   Water       The detector is configured to detect water. 
   Corrosive Fluids       The detector is configured to detect acids, alkalines, etc. 
   Petroleum Based Products / Fuels       The detector is configured to detect any manner of petroleum based liquids or fuels. 
   Other       Other unlisted detectable liquid type. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Detectable Liquid Features
   Detectable Liquid Features:       
   Your choices are...         
   Foam / Bubbles       The detector can work with liquids with foam or bubbles. 
   Dirty Liquids       The detector can work with dirty liquids. 
   Opaque Liquids       The detector can work with opaque liquids. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Also Detects Gases / Vapors?       The detector can also detect gasses or vapors. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

Liquid Temperature
   Liquid Temperature Range       The sample temperature range the detector can operate in. 
   Search Logic:      User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.

Output Options
   Output Options:       
   Your choices are...         
   Analog Voltage       Any analog voltage output. Output voltage is a simple (usually linear) function of the measurement. 
   Analog Current       Often called a transmitter. A current is imposed on the output circuit proportional to the measurement. Feedback is used to provide the appropriate current regardless of line noise, impedance, etc. Useful when sending signals over long distances. 
   Frequency / Modulated Frequency       Frequency or modulated frequency output (e.g. sine wave, pulse train, AM, FM). 
   Switch or Alarm Signal       The output is a switch or alarm. 
   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Detector Features
   Built in Alarm Indicator?       Built in audible, visual etc. alarm. Not just a switch or relay closure. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Discriminating (Selective) Sensor?       Distinguishes between different liquids / chemicals. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Intrinsically Safe?       The detector is for use in areas, which may have an explosive atmosphere. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Submersible?       Designed to be fully and continuously submerged in fluid. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
