I. Overview: 

 Widely used in a variety of liquid level measurement, such as oil, water, sewage, acids, alkalis and other liquid media. The use of intrinsically safe explosion-proof junction box and amplifier circuit, stainless steel guide rod and float. The wide range of product applications, and high reliability. 
 Second, technical parameters and indicators: 
 ◇ Output signal: 4 ~ 20mADC two-wire 
 ◇ Level range: H = 0.1m ~ 30m (greater than 6m require on-site fabrication and installation) 
 ◇ accuracy error: A grade: ± 5mm B grade: ± 10mm 
 ◇ Medium temperature: -20 ℃ ~ 150 ℃ 
 ◇ Working voltage: 24VDC 
 The product features: 
 ◇ can effectively overcome the suspended solids, foam formation of false level 
 ◇ float weight can be measured by the interface between two liquids 
 ◇ low cost, high reliability
