Typical Applications
The FP360 sc oil analyzer is an online oil-in-water analyzer designed specifically for monitoring trace mineral oil in water. It is used in municipal and industrial wastewater, water treatment and process water treatment (non-hazardous areas), industrial process monitoring, seawater desalination influent monitoring, membrane treatment, etc.
Principle of Operation
The FP360 sc oil analyzer is based on the fluorescence characteristics of PAHs and uses the UV fluorescence method to determine the concentration of polycyclic aromatic hydrocarbons in water. PAHs excited by UV light produce short delayed luminescence, and the light intensity is measured at a wavelength of 360 nm. By detecting the PAH concentration, this oil-in-water analyzer calculates the total oil content in the water body.

Case Studies
Municipal Wastewater Treatment · Controllers and Sensors — Application Case
Site Conditions
This is a Municipal Wastewater Treatment customer whose plant is at the inlet, biological and outlet stages of a municipal plant. The main task was online water monitoring with a controller and sensor combination.
The Problem
The difficulty lies in high solids and corrosive fractions, with large diurnal flow swings; at the same time effluent parameters drift and probes foul with sludge and biofilm. Specification therefore means matching each controller channel to its sensor type.
What We Did
We took a Hach channel approach — supplying against the Hach original part numbers. Delivery was built around matching each controller channel to its sensor type, with point-by-point checks on: stable compliance with Grade 1A discharge limits and online data reporting.
Operating Outcome
In service the system performs as intended — factory-matched combinations that make faults easier to locate, with routine maintenance falling noticeably.
Food & Beverage · Controllers and Sensors — Application Case
Application Context
dosing, pasteurising, filling and CIP stages is a typical Food & Beverage duty. The project started from Controllers and Sensors, focusing on online water monitoring with a controller and sensor combination.
Process Constraints
frequent cleaning demands instruments that withstand hot CIP/SIP caustic cycles, and syrups, dairy and beverages that scale easily, under strict hygienic requirements only amplify it. The Controllers and Sensors specification must therefore cover matching each controller channel to its sensor type.
Delivery Approach
Delivery was handled as the Hach channel — supplying against the Hach original part numbers. Execution centred on matching each controller channel to its sensor type, together with food-safety and hygienic design per 3-A / EHEDG.
Field Results
Operation shows the benefit clearly — factory-matched combinations that make faults easier to locate, with confidence in this measuring point improving markedly.
Chemical & Pharmaceutical · Controllers and Sensors — Application Case
Customer Profile
The typical setting in Chemical & Pharmaceutical is reactors, metering vessels and finished-product tanks. The measuring point is Controllers and Sensors; the focus is online water monitoring with a controller and sensor combination.
Key Difficulties
Conditions are highly corrosive media with solvents and crystallisation, partly in explosive atmospheres and, on top of that, corrosion plus Ex protection shortens instrument life and makes downtime costly, which a standard configuration cannot handle for long. The design therefore starts with matching each controller channel to its sensor type.
Implementation
The scope ran through the Hach channel: supplying against the Hach original part numbers. Technically it hinges on matching each controller channel to its sensor type, and on these requirements: Ex certification and GMP traceability of records.
Customer Benefit
In practice this means factory-matched combinations that make faults easier to locate, which cut the workload on the site maintenance team.
Power & Energy · Controllers and Sensors — Application Case
Project Background
The project covers boiler feedwater, turbine condensate and FGD/DeNOx systems. The work centres on Controllers and Sensors and the core task is online water monitoring with a controller and sensor combination.
Operating Challenges
The medium and duty are characterised by high temperature and pressure with both steam and saline water, and drift under high temperature and pressure, with very costly unplanned outages. So Controllers and Sensors cannot be specified generically — it calls for matching each controller channel to its sensor type.
Solution
The Ainstru engineering team worked through the Hach channel: supplying against the Hach original part numbers. The configuration involves matching each controller channel to its sensor type, with these requirements in view: compliance with power-industry codes and unit availability targets.
Results
Since start-up the system has run steadily; the practical result is factory-matched combinations that make faults easier to locate.
