FT-1000/FP-1000
FLOAT TYPE TANK GAUGES
GENERAL
The FT-1000 or FP-1000 series is a mechanical level gauge with afloat.
The FT-1000 is a conventional float-tape level gauge with its float
guided through the guide wires in standard practice.
The FP-1000 is used together with a seal pipe which completely
isolates gases and liquids in the tank from the level gauge. The FP1000 is suitable for the pressurized tanks or the corrosive services.
So it can be used for various applications.
Each FT-1000 or FP-1000 has a local indicator which indicates theliquid level in the unit of 1 mm. Each type can be equipped withvarious kinds of transmitters which output the alarm contact, pneumatic, electric or digital signal for remote liquid level monitoring.
Among various principles of level measurement, these cost effective
level gauges suitable for various applications have the most simple
and reliable construction easy for maintenance as well.

FEATURES❏ SIMPLE CONSTRUCTION
Pure mechanical action. Easy installation and maintenance❏ COST PERFORMANCE
Compared to other principles, relatively low-cost measurementof liquid level is possible.
❏ WIDE APPLICATION
FT-1000/FP-1000 cover from atmospheric tanks to pressurized
spherical tanks. Also, by selecting appropriate material, they canbe used for corosive liquids.
❏ TRANSMITTERS AVAILABLE
In addition to local liquid level indication, different types of transmitters, i. e. alarm contact(s), pneumatic, electric, digital serial
code, etc, can be provided for remote indication/contorol.

APPLICATIONS● GENERAL CONE ROOF TANKS, FLOATING ROOF TANKS FORCRUDE OIL
From crude oil tanks, intermediate tanks to final product tanks in
Oil refining plants.
● HIGH PRESSURE TANKS FOR LPG AND OTHERS
FT-1000 can cover upto 3 MPa pressure tanks. It is also used
for medium pressure cylinder tanks.
● HEAVY OIL TANKS FOR THERMAL POWER STATIONS
Utility tanks, Fire fighting water tanks● CORROSIVE LIQUID TANKS
Pipe sealed type FP-1000 covers even corrosive liquid tanks.
