Operating medium temperature:-196 to +400 million m³
Working medium pressure:0 to 35 MPa thous. t storage
Length of immersion part:60-8000 mm
Minimum density of the medium:300 kg/m3
Description
Ultrasonic level switch with a sensing element in the form of a fork is designed to work with media with a minimum density of 300 kg/m3. The main area of application is detection of liquefied gases such as natural gas (LNG) and broad fraction of light hydrocarbons (NGL).
The connection is made by a two-wire current loop circuit and a flip-over relay
Sensing element is made of stainless steel 12?18?10? and is therefore resistant to physical, chemical and temperature influences. An important advantage of SZHU-1-V is the ease of cleaning of the sensing element.
The device can be manufactured with two types of sensing elements
Standard fork (version for the majority of controlled media)
In the form of high-frequency fork. (version of the instrument for level control in media with increased free gas content).
