Introduction

The WaterLOG® H-3553/ Pressure Sensor is well known for its compact size and combination of a Bubbler and built-in pressure sensor. The H-3553 has also been referred to as a self-contained “smart” gas purge system, because it produces a precision constant mass flow of gas.

Designed to measure fluid levels in surface water, ground water and tanks, the H-3553 Modbus or Auto mode is enabled it will enter the RS-232 menu with any character sent to this port. uses a battery operated compressor to maintain pressure in an internal tank. A microprocessor determines how much pressure is needed in the tank, based on the current head pressure, to produce a constant bubble rate. The compressor and tank replace the dry nitrogen tank used in previous systems to ensure a safer site.

A sophisticated system of sensors and valves to regulate the bubble rate and purge pressure replaces the sight feed flow controller and pressure regulator (Conoflow system) used in previous systems. A purge feature, temporarily pumps up the tank and opens a valve to apply high pressure to the orifice line. This feature is designed to remove any sediment that may have collected in or around the outlet of the orifice line.

The H-3553 is a standalone system to be used with a Data Collection Platform (DCP). Additional programming options and an H-3553 built-in menu, make the XL series DCP’s a favorite when it comes to selecting a data logger to pair with this Bubbler.

Key Features:

•Easy to use stand-alone RS-232 menu setup

•Built in calibrated pressure sensor

•No external pressure sensor needed

•RS-485 MODBUS Client/Slave device (available in V1.3 or later)

Display Features:

•Continuous display readout always shows last measured value

•‘Read’ button causes the H-3553 to initiate a new measurement

•‘Purge’ button causes the H-3553 to initiate a line purge

•‘Tank Release’ button causes the H-3553 to release the pressure from the tank

•The adjust knob allows the user to manually set the stage and sensor SDI-12 address

Other Features:

•Provides a continuous gas flow

•Battery operated – Low power

•Microprocessor controlled, “smart” gas system

•One-piece manifold eliminates many potential sources of leaks

•Pressure gauge provides a visual indication of the tank pressure

•Hydrophobic intake membrane, protects compressor

•All components are easily accessible for inspection and maintenance

Product Description

It is important to familiarize yourself with the connections before installing a product at the site. Below are standard connections found on the H-3553.

Enclosure Breather

RS-232 Menu Setup Port & Cable Connection

Power & Communications Main Interface Connection

Atmospheric PSI Vent for Sensors

Compressor Air Intake Desiccator Connection

Constant Bubble Out Orifice Line Connection 1/8 inch FNPT

Compressor Power (Connect First)

Initial Testing

Before installing the H-3553 in the field, it is a good practice to test the system in the shop or lab. This will help preparations for a successful field install.

Power Up

Follow these steps to power up the H-3553:

1.Apply +12v to the “Compressor 12VDC” terminal connections

2.Referring to Table 2-1, connect +12 VDC, GND, and SDI-12 data connections of the 7 wire Main I/O sensor interface pigtail cable to a SDI-12 master device, such as a WaterLOG® XL series DCP.

3.Verify the connections Table 2-1, and then connect the Main I/O sensor interface pigtail cable to the H-3553 via the 7 pin “Sensor Interface” military grade connector.

4.At power up, the H-3553 will take an initial atmospheric measurement (listen for a “click” while the 6 sensors are switched to atmosphere) and then if needed the compressor will turn on to initialize the tank

pressure.

			Getting Started
Using the Display	Table 2-1: Main I/O Sensor Interface Cable
The H-3553s display has a ‘Read’ button that		Colors	Signal	Cable/Bulkhead
when pressed will cause the unit to initiate a new		Red	+12 VDC	F
measurement and update the display. Measurement
		Black	GND	E
requests from an attached SDI-12 data logger will
		Yellow	SDI-12 Data	G
also cause the display to update.
		Blue	4-20mA +	C
If the ‘Read’ button is pressed and held until
		Green	4-20mA -	D
the display starts flashing, the Adjust screw may
		Orange	RS-485+	A
be turned to increase or decrease the current
		Brown	RS-485-	B
stage value. Turning the Adjust screw slowly
will change the hundredths (or thousandths
based on the digit setting) digit while turning
the screw fast changes the ones digit. This
allows one control to make both fine and course
adjustments.

If the ‘Read’ button is held down while the

H-3553 is being powered up, the display will show the current SDI-12 address. The SDI-12

address may be changed using the Adjust screw. Turning the Adjust screw will change the address in the range of 0 to 9. When the Read button is released the new SDI-12 address is saved and the display switches to the normal stage readout. To change the SDI-12 address again, the power must be disconnected and the special power-up sequence repeated.

When the ‘Purge’ button is pressed a new measurement will be initiated; following the measurement, a line purge will begin. For more information see the Purge section in Chapter 4.

When the ‘Tank Release’ button is pressed the valve holding the air in the tank will be opened, allowing the air stored in the tank to be released. This button can be useful when troubleshooting the unit.

Make Measurement

Using a SDI-12 master device, like the XL series DCP, send the “0M!” measurement command to the H-3553. Wait about 6 seconds, and then send the “0D0!” data command and verify the data retrieved with the example below.

Data format: “a + A.AA + B.BBB + CC.C + DD.D + E.EE + FF.F”
a = SDI-12 sensor address
A.AA = Stage (Feet)
B.BBB = Pressure (PSI)
CC.C = Temperature (°C)
DD.D = Sensor Interface Battery (Volts)
E.EE = Tank Pressure (PSI)	7
F.FF = Compressor Battery (Volts)

Example: “0 + 1.35 + 0.585 + 19.8 + 13.6 + 3.55 + 12.3”

03 /INSTALLATION

8

Installation

The WaterLOG® H-3553 is a system with a fully integrated digital pressure transducer specifically designed for water level monitoring. The H-3553 directly measures dry gas over a broad temperature range.

WARNING! Before proceeding with the installation, please consider the following site preparation steps to help prevent problems later.

Water Depth

Table 3-1 shows the maximum pressure to which the H-3553 is factory calibrated to measure. The sensor can survive temporary operation up to twice the maximum rated pressure for the model’s range. However, any measurements made beyond the rated pressure will be inaccurate.

*NOTE: Depth calculations are derived from the standard equation that one PSI is

generated by a column of water 2.3067 feet deep.

Table 3-1: Models Pressure Ranges

Model	Pressure Range	Water Depth Range*	Accuracy
H-3553-15	0-15 PSI	0-34.60 Feet	+/- 0.007 Feet
H-3553-30	0-30 PSI	0-69.20 Feet	+/- 0.014 Feet

Mounting

Consideration should be taken in properly mounting the H-3553 system. First, attach the included mounting feet to the H-3553 enclosure. Mount the H-3553 in a location where it will not get jarred or will shift during operation.

When possible mount all equipment with connectors pointing down so that moisture or condensation that could rest on the connectors does not penetrate the inner components of the equipment. Also, specifically with the H-3553, having it mounted vertically helps prevent moisture from migrating to the valves. If moisture does migrate, it will migrate first at the bottom of the tank and near the nylon plug.

Desiccator

Generally, an external desiccator is required to dry the compressor intake air. The desiccator prevents accumulation of moisture in the tank, manifold and other areas in the system. Connect the output of the desiccator to the port marked “Inlet”. Desiccators which employ “indicating” silica gel have the advantage of visually showing the status of the desiccant. As the gel becomes saturated with moisture the gel changes from blue to pink.

Orifice Line

The position and installation of the orifice line is vital to a successful and accurate H-3553 installation. These are just a few of several things to consider when installing or checking an orifice line installation. Refer to “Application Note 1005” for more detailed information about orifice line installation.

	Be sure the water current or flow is not pushing against the end of the orifice line, as it will cause a	9
	pressure to be placed on the line that is not related to the water depth. Also, be sure the water current or
	flow is not pulling or drawing from the end of the orifice line, as this will cause a false lower pressure on
