General Specifications*

Temperature

Standard range is -40°F to 176°F, -40°C to 80°C.

Accuracy

Accuracy depends upon proper gauge sizing and is typically ±5% of dial indication. Accurancy may be less due to variations in liquid temperature. Accuracy may be less for some tank shapes and sizes. Accuracy may be less near full and empty. Accuracy may be less if tank is not level. This gauge is not to be used for filling. All accuracy estimates are expressed as a percent of full scale.

Shock & Vibration

Suitable for mobile service applications.

Maximum Pressure

375 psig [25,8 Bar]

UL Listing

UL listed for NH3 service.

 

When Ordering Specify:

1. Gauge head size, Junior or Senior.

2. Tank diameter as shown on nameplate.

3. Mounting location (top, side, end, or angle),

4. If gauge is angle mounted, state degree of angle above or below the horizontal centerline.

5. If gauge is end mounted, state the shape of the tank head, hemispherical or semi-ellipsoidal.

6. the "H" dimension (distance in inches from the surface of the tank to the gasket surface on the riser).

To order a replacement gauge, simply furnish the information stamped on one of the flat sections on the side of the gauge head as shown in the example.

Note: For installation instructions see MS-501/502 (mounting standards).

CAUTION: For applications where NH3 may include small amounts of water or chemical additives, see model A6480 with improved corrosion resistance.
