Introduction

Principle & Structure

LV71 series flanged static pressure liquid level transmitter is based on ceramic capacitor technology. When the liquid level increases, the pressure on the ceramic capacitor increases, which increases the capacitance value, which is proportional to the liquid level.

Features

● Flange installation, strong overload capacity

● Good stability, due to 0.1% of full scale per year

● Long life, can be used for continuous monitoring of liquid level

● Strong anti-interference ability, extremely high precision and repeatability can reach 0.2, 0.5 grades

● 4-20mA/1-5 analog output optional

●The zero point and full scale can be adjusted on site. Ceramic measuring interface has good corrosion resistance

application

Suitable for liquid level monitoring in medium and large tanks

Suitable for viscous and slurry media, strong corrosive liquids, media rich in particles, not easy to block

Mainly used in wastewater / water purification, shipbuilding, generator equipment, petrochemical, food, electronics, dyeing and finishing, chemistry, rubber and plastics, hydraulic machinery, chemical and pharmaceutical industries.
