What is the DAQ System For Filter?

The DAQ System For Filter is a PC-based Data Acquisition and Control system designed for conducting collapse, life, and efficiency tests on hydraulic and industrial filters. It monitors differential pressure, flow rate, and temperature while providing PID closed-loop control of the AC drive and automated valve operation.

What parameters does the system monitor?

The system monitors Differential Pressure across the test filter, Flow Rate (up to 4500 LPH), Temperature in the oil bath, and Level Sensors. All parameters are displayed in real time on the GUI schematic screen.

Does the system support PID control?

Yes. The DAQ system includes PID closed-loop control for maintaining constant flow rate via the AC drive motor and constant temperature in the oil bath. Control actions are taken automatically based on sensor feedback.

The DAQ System for Filter is a PC-based Data Acquisition & Control platform built specifically for conducting collapse tests and life & efficiency tests on hydraulic, lubrication, and industrial filters. The system continuously monitors Differential Pressure across the test filter, Flow Rate, and Temperature in the oil bath, providing a complete picture of filter performance throughout the test cycle.

The hardware layer interfaces with pressure sensors, temperature sensors, flow sensors, on/off and solenoid valves, level sensors, and the AC drive motor. A PID control loop maintains constant flow rate by automatically adjusting the AC drive speed, while a separate PID loop maintains constant oil bath temperature. Valve sequencing for oil sampling is fully automated from the GUI.

One screen. Every parameter. Full PID control — no manual intervention during the test cycle.

The application software is GUI-driven with an on-screen schematic of the rig showing live values at every sensor point. On-screen error reporting and a health-check routine validate system readiness before each test run.

Feature · 04

Constant Oil Bath Temperature

Separate PID loop maintains the oil bath at the specified test temperature. Temperature sensor feedback drives a heater or cooler as required, ensuring the fluid viscosity remains consistent throughout the test.

In Depth

The complete technical read.

Engineering narrative for test engineers specifying a filter DAQ system.

01 — Purpose

Why a dedicated DAQ system

Filter collapse and life tests require conditions that remain constant across potentially hundreds of hours. Manual control introduces variability that corrupts results and makes test-to-test comparison unreliable. A dedicated DAQ and control system eliminates operator variability, ensures consistent conditions, and provides a continuous time-stamped record of all parameters.

02 — Flow PID

PID control of flow rate

As a filter loads up, its restriction rises and would reduce circuit flow without active control. The PID controller continuously compares measured flow against the setpoint and adjusts AC drive speed to compensate — maintaining constant flow regardless of filter condition throughout the test.

03 — Temperature PID

PID control of oil bath temperature

Fluid viscosity is a function of temperature. The temperature PID loop monitors the oil bath sensor and drives a heater or cooler to hold the setpoint — ensuring viscosity remains consistent across the full test duration and eliminating a key source of result variability.

04 — Valve Control

Automated valve sequencing

Oil sampling, circuit filling, and drain sequences are fully automated. The operator selects the sequence from the GUI; the software drives solenoid and On/Off valves in the correct order. This eliminates sampling errors from incorrect manual valve operation and provides consistent sampling for particle count analysis.

05 — Health & Diagnostics

Health check & error reporting

A pre-test health-check routine polls every sensor, checks valve responses, verifies AC drive communication, and confirms adequate fluid levels. Any fault is reported on screen before the run starts — preventing aborted tests and protecting the filter under test.

FAQ

Common questions.

Q · 01What tests can the system run?

The system is designed for filter collapse tests and filter life/efficiency tests. It monitors differential pressure, flow rate, and temperature throughout, with automated step-up flow profiles for efficiency testing.

Q · 02What is the maximum flow capacity?

The standard system supports up to 4500 LPH. Custom configurations for higher or lower flow ranges are available by specifying the appropriate pump and flow sensor.

Q · 03Does the system log data automatically?

Yes. All parameters are time-stamped and logged continuously from test start to finish. Post-test reports can be generated directly from the application software.

Q · 04Can the flow rate be varied during the test?

Yes. The step-up flow rate feature allows the system to automatically increase the flow rate at programmed intervals, logging all parameters at each step. This is used for filter efficiency and Beta ratio testing.

Q · 05What sensors does the system interface with?

Pressure sensors (for differential pressure), temperature sensors (oil bath), flow sensors, level sensors, On/Off valves, solenoid valves, and the AC drive motor controller.

Q · 06What after-sales support does Neometrix provide?

Installation, commissioning, operator and software training, preventive maintenance, and on-site service. Standard 12-month warranty on hardware. Annual maintenance contracts available.
