FYRITE SAFETY PRECAUTIONS

20 16

%CO

The operator (s) of this instrument should thoroughly familiarize themselves with the applicable safety precautions before handling or using the FYRITE for gas analysis.

Review Figures 1a,1b, 1c and 1d on this page. Make certain to follow the steps outlined below and read the ﬂ uid handling precautions for your personal safety.

1) Always use protective equipment such as safety goggles, gloves, and protective clothing as illustrated in Figure 1a.

2) Read the instruction manual thoroughly. When ﬁ lling the FYRITE with the appli- cable ﬂ uid charge, use safety equipment and perform the operation in the vicinity of running tap water (Figure 1b).

3) The FYRITE ﬂ uid should always be in the bottom reservoir before and during sample introduction to the FYRITE. When venting the FYRITE to atmosphere, hold the instrument in the vertical position and at a location away from your face (Figure 1c).

4) NEVER vent FYRITE in the inverted position (with the plunger facing downward). This will cause ﬂ uid to spill, which is corrosive and contains harmful ele- ments (Figure 1d).

NOTE: In the event of ﬂ uid spill - refer to Section 2.2 (FYRITE Handling

Precautions). For Maintenance - refer to Section 6.0.

OPERATION/MAINTENANCE

BACHARACH FYRITE MODELS

CO2 and O2 INDICATORS

1.0 DESCRIPTION (Refer to Figure 1)

The FYRITE employs the well-known “Orsat” method of volumetric analysis involving chemical absorption of a sample gas, such as carbon dioxide or oxygen. The reagent used to absorb carbon dioxide (CO chloride (blue) is the absorbent for oxygen (O that the absorbing ﬂ uid is also used as the indicating ﬂ uid so that one vessel takes the place of both measuring burette and absorption pipette.

The body of the FYRITE is molded of clear high-strength plastic, comprises top and bottom reservoirs and a center tube connecting the two reservoirs. The bottom of the lower reservoir is sealed off by a synthetic rubber diaphragm that rests on a perforated metal plate. The upper reservoir is covered by a molded plastic cap that contains a double -seated plunger valve. A spring holds this valve against a carefully ﬁ nished seat in the top cap providing a perfect seal which makes the instrument spill-proof in any position. When the valve is partially depressed, the entire instrument is open to the atmosphere and the instrument is, of course, is no longer spill-proof.

The bottom reservoir is ﬁ lled with the absorbing ﬂ uid, which extends about 1/4 inch into the bore of the center tube when the instrument is held upright. The scale position, mounted to one side of the center tube, is adjustable.

CAUTION

Corrosive ﬂ uid is contained inside unit, instructions should be thoroughly read before operation is attempted.

2.1 Pre-Operational Check

To ensure proper FYRITE operation and reliable results, check the following:

(a) With FYRITE vented and in a vertical position, it should be possible to adjust

scale zero to the top of the ﬂ uid column. Refer to FYRITE Operation for proper setup (Section 3.0 Steps 1 through 5). If this is not possible, add or remove a small amount of ﬂ uid per Section 6.1.

Instruction 0011-9026 Page 1

(b) FYRITE Fluid Strength

To check ﬂ uid strength.

NOTE: When repeating procedures as outlined in Section 3.0 Steps 7 through 9 (absorbing and reading percent O sorbing and reading percent CO2) and before venting FYRITE

and ab-

to atmosphere for next sample, if the reading increases by more than 1/2 percent for either CO

or O2, replace the ﬂ uid.

It is often desirable to check ﬂ uid strength before taking the FYRITE to a location where it will be used. It can be tested on sample atmospheric air (which contains

10. This step completes CO2 or O2 FYRITE gas sample analysis. A few points to remember when reading the FYRITE: (a) FYRITE accuracy is within ±1/2% CO2 or O2 compared to actual value.

(b) Always handle FYRITE by ﬁ ns to ensure body heat is not absorbed by ﬂ uid.

slightly but longer delays may cause substantial error.

(d) The FYRITE is calibrated to indicate on a “dry” basis for ﬂ ue gas samples,

which are normally fully saturated with moisture. Failure to artiﬁ cially moisten wool packing in Filter Saturator Tube when actual sample is not fully saturated will cause FYRITE to read slightly low.

Therefore, make certain wool packing in Filter Saturator Tube is sufﬁ ciently

moistened with water for accurate results on non-ﬂ ue gases. Avoid excessive moisture which can be drawn into the Aspirator Bulb and forced into the FYRITE during sampling.

CAUTION

Never depress plunger valve to vent FYRITE in the inverted position. This will cause ﬂ uid to spill, which is corrosive and contains poisonous elements. In the event of a spill, read Instructions in Section 2.2 FYRITE ﬂ uid handling precautions.

3.1 Determining CO2 and O2 FYRITE Fluid Strength

FYRITE Fluid strength can be conveniently checked immediately after the ﬁ rst sample reading. Without venting, repeat the absorbing operations (Steps 7 through

9) by inverting FYRITE again and positioning upright until all ﬂ uid drains to the bot-

tom reservoir. Observe scale reading. An increase of more than 1/2% CO second reading as compared to the ﬁ rst indicates a need for ﬂ uid replacement.

or O2 in the

3.2 Operating Precautions to Ensure Maximum Accuracy

Locate top of ﬂ uid column (refer to Fig. 11). The surface at the top of the ﬂ uid column (meniscus) in the small, center bore will be dish-shaped as shown in Figure 11. Either the high or low point of this dish- shaped surface may be used to locate top of ﬂ uid col- umn providing the same point is always used both for setting scale zero and reading percent CO other will cause an error.

Best practice is to use high point of this ﬂ uid surface just at the small center bore wall. In setting scale zero or reading percent CO level with eyes and sight across scale to top of ﬂ uid column.

or O2. Obviously, using high point for one operation and low point for the

or 02, hold FYRITE vertically and

3.2.1 Draining Fluid Droplets

%CO2

For maximum accuracy, it is important to form the habit of follow ing a standard procedure in this operation and to use the same procedure both before adjusting scale zero and before reading percent CO

or O2 .

3.3 FYRITE Temperature

The FYRITE temperature should be at or close to the temperature of the working environment where the analysis is being made and should not be subject to sudden temperature changes. If FYRITE is carried from cooler to warmer location or vice versa, expose FYRITE to new temperature condition to permit uniform temperature stabilization. Usually 15 or 20 minutes will sufﬁ ce, except when extreme temperature variations are involved. Temperature stabilization can also be accelerated by inverting FYRITE frequently.

3.3.1 Temperature of Gas Sample

The gas sample as it enters FYRITE should be cooled (or warmed if sampling cool gases) to same (ambient) temperature as the FYRITE.

Capacity of Standard Aspirator Bulb and Sampling Assembly (Part # 11-7029) to cool the gas sample is sufﬁ cient if the temperature of gas being sampled does not exceed 850°F (454°C), even where a large number of consecutive samples are required if there is an interval of not less than 5 minutes between samples.

FYRITE indicators operate over a wide temperature range. They may be exposed to ambient temperatures from –30° to 150°F (–34° to 66° C). Gases up to 850° F (454° C)

may be tested with Standard Aspirator Sampling Assembly (11-7029).
