Run a Hydrostatic Test on a FieldLab

Run a Hydrostatic Test on a FieldLab

Use a FieldLab and one or more Field Gauges to perform a Hydrostatic Test.

Overview

This article will show you how to use a FieldLab and one or two Field Gauge LC20s to perform a Hydrostatic Test with one pressure reading and up to two separate temperature readings.
  1. The FieldLab will read pressure.
  2. The Field Gauge(s) will read temperature(s).
  3. The Field Gauge(s) will transmit the temperature readings wirelessly to the FieldLab.
  4. The FieldLab will save all temperature and pressure readings to one data set, which can be downloaded to a PC and exported in .csv and .pdf file format.

Example setup with one temperature reading and one pressure reading:





Things you will need to perform the test

  1. A PC running FieldLab Desktop software to create your Hydrostatic Test. 
  2. FieldLab with wireless module running firmware 1.127 or later. 
  3. At least one Field Gauge LC20 with W1 radio and thermal probe.
If you have already purchased a Ralston Hydrostatic Test Kit you will have everything you need (PC not included).

1. Create your custom Hydrostatic Test and add it to your FieldLab


2. Confirm that the FieldLab and Field Gauge(s) are set to the same wireless radio channel.

Field Gauges and FieldLabs that are equipped with a W1 Radio each have 16 radio channels (11 through 26). All devices must be set to the same channel in order to communicate with each other. The factory default for all Ralston devices is channel 26. 

3. Connect FieldLab and Field Gauge to the vessel/system being tested.

Connect the FieldLab to the pressure opening, and the Field Gauge(s) to the temperature well and ambient source, if applicable.

4. Power on the Field Gauge.

You should see a blinking link icon in the upper-right hand side of the screen. This indicates the radio is on and looking for another device to connect to. 

5. Activate the Hydrostatic Test on the FieldLab

1: Select the MENU button to access the Menu.
2: Select the Right Arrow button to view Test Modes.
3: Select the Down Arrow button to scroll to the Hydrostatic Test you wish to use.
4: Select the center Zoom button to ACTIVATE the Hydrostatic Test.

6. Select the Field Gauge you want to connect with wirelessly on the FieldLab.

Once the FieldLab and Field Gauge(s) connect wirelessly, select the Field Gauge you wish to use for Temperature 1 (T1).

You can identify every wireless Field Gauge connected to the FieldLab by its serial number. If there are other Field Gauges with wireless radios on and within range, they may appear on the screen as well.

If your test specifies two temperature readings, repeat Step 6 for Temperature 2 (T2).

7. Select the Log Button to START LOGGING.

8. Select the Log Button to STOP LOGGING at any time.

The FieldLab will continue logging until you select the Log Button to STOP LOGGING, or until the duration specified in the test has been met for an automatic stopping point.

Next Steps:
Some things you may want to do after you've performed a Hydrostatic Test.
  1. Import your Data Sets from FieldLab.
  2. Export Data Sets from FieldLab Desktop to .csv and/or .PDF file formats.

You can also log pressure and temperature readings for a Hydrostatic Test directly to your computer. Learn how:
