EASY OIL MONITORING ANYPLACE ANYTIME

1. Tank Level Gauge

1. HM720B  - a LCD touch screen displays all information of tank storage
2. HM520S - a Sensor of oil tank has one of the most accurate technology to measure the amount of liquid in a tank at all time. 

DMT520S, Automatic Tank Gauge(ATG), is a magnetostrictive sensor to measure the level of oil, the level of water and the temperature of the content in a storage tank.It has highly accurate Fuel-Management-System and Leak-Detection-System.

• Ultramodern-precision : A resolution of 0.001mm
• Leak detection of oil or liquid contents : 0.8L/1 hour
• Distinguished durability(Made of stainless steel body)
• Easy installation- Less procedure than a previous model.
• The Small floaters- one of the smallest in the market.
