Handheld Hydrant Pitot with Case

Using Akron Brass's Handheld Pitot for taking a flow reading is straightforward yet crucial for obtaining accurate measurements. Below is a detailed guide on its features, usage, and maintenance.

Features

• Heavy-duty aluminum blade: Ensures durability and longevity.
• Stainless steel pitot tube: Provides accurate measurements and resistance to corrosion.
• Numbered increments on the pitot blade: Enhances measurement precision.
• Conveniently located bleeder valve: Allows for easy pressure release.
• 3.5" liquid-filled gauge: Measures 0-160 PSI (0-1100 kPa) for reliable readings.
• Carrying case: Facilitates safe storage and transport.

What is it?

The Handheld Hydrant Pitot is a specialized instrument used to measure the flow rate and pressure of water from fire hydrants. It is designed to provide accurate readings that help in assessing the performance and maintenance needs of hydrants.

How is it used?

To use the Handheld Hydrant Pitot:

1. Attach the pitot tube to the hydrant nozzle.
2. Open the hydrant to allow water flow.
3. Read the pressure gauge to determine the flow rate.
4. Use the numbered increments on the blade for precise measurements.

Who uses it?

This tool is primarily used by:

• Firefighters: To ensure hydrants are ready for emergency use.
• Water utility workers: To monitor and maintain hydrant performance.
• Municipal maintenance teams: For routine checks and repairs.

Installation Requirements

The Handheld Hydrant Pitot does not require any tools for installation. It is designed for easy, manual operation directly on the hydrant.

Maintenance Information

Regular maintenance includes:

• Cleaning the pitot tube and blade: To prevent debris buildup.
• Checking the gauge: To ensure it is functioning correctly.
• Inspecting the bleeder valve: To confirm it operates smoothly.

Storage Information

Store the Handheld Hydrant Pitot in its carrying case to protect it from damage and contamination. Keep it in a dry, cool place to maintain its integrity.

What's Included?

• Handheld pitot tube
• Aluminum blade
• Certified calibrated gauge
• Carrying case

Proper Use Instructions

Using the Handheld Pitot correctly is essential for obtaining accurate readings. Here are the steps:

1. Positioning: Stand on the right-hand side of the water stream with the pitot in your right hand, and your right thumb above the air/water bleed button. Hook three fingers of your left hand over the handle of the pitot between the pitot blade and gauge.
2. Inserting the Blade: As you insert the blade into the water stream, use extreme caution as the pitot will kick back. It takes practice to hold the tip of the blade in the center of the water stream. Steady the Handheld Pitot to prevent the force of the water from affecting the reading.
3. Bleeding Air: After obtaining a secure grasp of the pitot tube, press the air/water bleed button with your thumb as the pitot tube is being placed in the water stream. This removes all air from the static pressure circuit of the pitot. The liquid-filled gauge minimizes needle fluctuation.
4. Reading and Recording: Place the pitot blade tip opening in the center of the water stream, held away from the hydrant outlet or nozzle tip, approximately one-half the diameter of the opening (e.g., for a 2-1/2 inch outlet, the distance would be 1-1/4 inches). Read the pressure gauge and record the pressure reading. Refer to the attached table for gallons per minute (GPM) or flow in kPa.
5. Post-Test: After the test is complete, press the air/water bleed button to allow all water to drain before storing the handheld pitot in its case.

By following these steps, you ensure accurate readings and maintain the integrity of the Handheld Pitot. Akron Brass's Hydrant or Apparatus Flow Test Kits may also be used for comprehensive testing.
