Inline Acid Alkali Concentration Meter

Inline Acid and Alkali Concentration Meter

The Sper Scientific Inline Acid and Alkali Concentration Meter is a sophisticated digital instrument engineered for the precise, real-time measurement of acid and alkali concentrations directly within industrial pipelines. This smart meter eliminates the need for manual sampling and offline analysis, providing continuous, reliable data for process control.

Advanced Measurement Technology At the heart of this meter is a state-of-the-art digital inductive conductivity sensor. This non-contact technology is exceptionally durable and resistant to fouling and corrosion, making it ideal for harsh chemical environments. It works by inducing a current in the solution and measuring the resulting conductivity to determine the concentration of specific chemicals.

This advanced sensor can accurately measure a wide range of solutions, including:

• Acids: Hydrochloric Acid (HCl), Nitric Acid (HNO3), and both dilute and concentrated Sulfuric Acid (H2SO4)
• Alkali: Sodium Hydroxide (NaOH), Potassium Hydroxide (KOH)
• Salts: Sodium Chloride (NaCl)

In addition to concentration, the meter simultaneously measures temperature, which is crucial for accurate, temperature-compensated conductivity readings.

Designed for Demanding Industrial Applications This concentration meter is built for reliability in challenging industrial settings. Its robust design ensures continuous, stable performance where precise chemical concentration control is critical. Key applications include:

• Thermal Power Generation: Monitors water purity and chemical levels in boiler systems to prevent corrosion and scale buildup.
• Chemical Manufacturing: Ensures product quality and process efficiency by maintaining precise reactant concentrations.
• Ion Exchange Processes: Critical for monitoring the regeneration of ion exchange resins. It accurately measures acid and alkali concentrations in the regenerating liquid, ensuring efficient and complete regeneration for high-purity water production.
• Pipe Pickling: Used to control the concentration of acid solutions during the pickling process for boiler pipes, ensuring effective cleaning without damaging the infrastructure.

Features and Benefits

• Real-Time, Continuous Monitoring: Provides instant feedback on process chemistry, allowing for immediate adjustments to maintain optimal conditions.
• High Accuracy: Delivers precise measurements (±1%FS) for tight process control and consistent product quality.
• Durable and Low Maintenance: The inductive sensor design minimizes contact with the process fluid, reducing wear and maintenance requirements.
• Versatile Measurement: A single device measures multiple chemical concentrations (HCl, NaOH, H2SO4, etc.) and temperature.
• Seamless Integration: Features dual 4-20mA current outputs and an RS485 communication interface for easy integration into existing PLC, DCS, and SCADA systems.
• Automated Control: Two programmable relays (5A 250V AC / 5A 30V DC) can be used to trigger alarms, pumps, or valves when concentrations go outside set points.
• User-Friendly Operation: A clear interface simplifies setup, calibration, and monitoring, making it easy to operate.
• Robust Construction: Housed in a durable IP65-rated enclosure (144x144x104mm), it is protected against dust and water ingress, ensuring long-lasting performance in industrial environments.
