Level Transmitter with Built-in Stilling Well

-------------------------------------------------------

Manufacturer: Omega(USA)

Model: LVCN80

Introduction:

     The LVCN-80 level transmitter is the low cost OEM and process solution for continuous level measurement. The transmitter is best applied in atmospheric vessels which contain non-coating or scaling type liquids including water, acid and chemical solutions. The measurement tube also serves as a built-in still well to help separate the point of measurement from any surface foam caused by process agitation. The minimum length of the tube is 12 inches and the maximum length is 10 feet. Industrial liquid examples include sulfuric acid, ultrapure water and nitric acid. A sound wave is pulsed five times per second from the base of the transducer. The sound wave travels down the measurement tube and reflects against the process medium before returning back to the receiver. The electronics measure the time of flight between the sound generation and the receipt, and translates this figure into the distance between the transmitter and the process medium below.
