1. INTRODUCTION

Pressure measurement is an important aspect of manufacturing.

This manual describes the basic operation of the Ashcroft TC

Tank Level Gauge, Designed specifically for vented tanks, the

following instructions should be followed to ensure effective

operation of the gauge.

[Before Using the Pressure Gauge]

It is highly recommended that this instruction manual will be

thoroughly reviewed to prevent improper instrument handling

and/or implementation. Consult Ashcroft on related topics not

covered within this document.

2. APPLICATION

The TC Tank Level Gauge continuously measures liquid

contents of any shape of storage tank or vessel, while its

integral capillary line facilitates remote mounting/reading of

the indicating dial. This gauge offers internal or external tank

mounted seal housing, and multiple mounting options.

This product was designed with a 160mm analog dial. Dials are

graduated in units to user specifications and are often marked

with radial lines to denote critical tank levels.

The power required to operate the TC Tank Level Gauge is

derived from the pressure exerted by the head of liquid within

the tank (hydrostatic pressure). This pressure is sensed by a

stainless steel diaphragm incorporated into the seal housing;

pressure is then conveyed by capillary line to a capsule that

drives the indicating pointer.

Deflection of the capsule within the indicator actuates a

precision mechanism, which moves the a pointer over a

calibrated scale. The transmitting diaphragm, capillary and

indicator capsule together form a sealed system, which is

thoroughly examined for leaks. No attempt should be made

to disconnect the capillary from the instrument, except for

mounting; this minimizes the risk of leaking and/or malfunction.

3. TRANSPORTATION, STORAGE & UNPACKING
