MODEL 28PU
HYDROSTATIC TANK CONTENTS GAUGE

Hydrostatic tank contents gauge


The 28PU gauge uses the hydrostatic principle of proven reliability and simplicity and requires no power supply. This method requires minimum installation time and gives important advantages in the safe measurement of volatile liquids.
By operating a small hand pump, fixed at the bottom of the gauge, charges the system with air under pressure. The liquid is displaced from the balance chamber at thebottom of the tank, while excess air escapes via the tanks vent.
The resulting pressure in the balance chamber is indicated by the gauge and is proportionate to the head of liquid in the tank.

MODEL 28PUE
HYDROSTATIC TANK CONTENTS GAUGE

Hydrostatic tank contents gauge


The 28PUE gauge uses the hydrostatic principle of proven reliability and simplicity, with push to read electric pump using 4 AA batteries or mains power supply via plug in 6v adaptor.
This method requires minimum installation time and gives important advantages in the safe measurement of volatile liquids.
The resulting pressure in the balance chamber is indicated by the gauge and is proportionate to the head of liquid in the tank. The gauge can be mounted at any position, and may be disconnected at any time without upsetting the calibration.


MODEL FSU LD101
TANK MONITORING WITH FLOAT OPERATED ALARM

Tank contents monitor with alarm


The FilSafe Tank Monitoring Alarm Unit LD Series 101, provides an Over-Fill level alarm for 1 tank, and is mostly used in Diesel Oil or Water tanks. The unit comes complete with a 1 metre adjustable level float switch that makes this a highly reliable Over-Fill alarm system.

• Helps to avoid Liquid Spillage
• Continuously monitors tank
• Mains Powered
• Built in Sounder


MODEL 38
BATTERY OPERATED LIQUID LEVEL GAUGE

Battery operated liquid level gauge


The Model 38 gauge uses the hydrostatic principle of proven reliability and simplicity, with a push to read electric pump using 4 AA batteries.

The gauge unit can be mounted in any position and may be disconnected at any time without upsetting the calibration. Maintenance is not normally required, except battery replacement, as there no moving parts external to the gauge unit.
