How to Select Industrial Clamp-on Ultrasonic Flowmeter?

How to Select Industrial Clamp-on Ultrasonic Flowmeter?

Clamp-on ultrasonic flowmeters are non-invasive devices used to measure the flow rate of liquids in pipes without the need for cutting into the pipe or stopping the flow. They work on the principle of ultrasonic transit-time flow measurement, which involves sending ultrasonic signals through the fluid and measuring the time it takes for the signals to travel between two transducers. By comparing the upstream and downstream transit times, the flowmeter can calculate the velocity of the fluid and, subsequently, the flow rate.

Industrial Syringe Pump Basics: Accuracy/Precision, Resolution and Flow Rate Calculation

Industrial Syringe Pump Basics: Accuracy/Precision, Resolution and Flow Rate Calculation

The resolution of industrial syringe pumps refers to the smallest increment of movement or volume that the pump can achieve. It is typically specified by the manufacturer and is important for applications requiring precise control over fluid delivery. To calculate the resolution of a syringe pump, you need to know the steps per revolution of the motor (if it's a stepper motor-driven pump) or the linear resolution of the pump mechanism. The linear resolution is usually given in units of distance per step (e.g., mm/step or µm/step). In this article, the basics of typical industrial syringe pumps, namely, the accuracy and precision, resolution and flow rate calculation (stepper motor driven), are briefly reviewed.

Practical Fluidic Interface Guide for Electric Rotary Valves in Laboratory Automation

Practical Fluidic Interface Guide for Electric Rotary Valves in Laboratory Automation

The electric rotary or multi-channel switching valve is a stepper motor-driven fluid handling valve designed for automated fluidics applications. This precise rotary valve automates the routing of fluidic volumes, allowing for the handling of aggressive fluids and switching flow directions as needed. For instance, in a multi-channel distribution valve, a common central port connects the stator and rotator, enabling the switching of flow direction between different ports with a rapid response time of less than 120ms for adjacent ports. This switching valve can communicate through RS-232, RS-485, or CAN interfaces, allowing for multi-valve arrangements of up to 15 valves in one group. See Figure 1 for the wiring instruction. It supports group control and individual addressing, making it versatile for various automation needs. The wetted materials in the flow path are PCTFE/Sapphire and can be customized upon request.

High-Performance Liquid Chromatography (HPLC) is a powerful analytical technique used to separate, identify, and quantify components in a mixture. It operates on the principle of chromatography, where the sample is dissolved in a solvent (mobile phase) and passed through a column packed with a stationary phase. The components of the sample interact differently with the stationary phase, causing them to separate based on their respective chemical properties, such as size, polarity, and affinity.

Peristaltic Metering Pump Types and Their Working Modes

Peristaltic Metering Pump Types and Their Working Modes

One of the key advantages of peristaltic pumps is their ability to handle delicate and viscous fluids without damaging them. Unlike other types of pumps, the flexible tubing used in peristaltic pumps does not come into contact with the fluid, which means that there is no risk of the fluid being damaged or contaminated.  Peristaltic pumps are also known for their reliability and durability. They are simple in design and have few moving parts, which means that they require minimal maintenance and have a long lifespan. They are also able to operate in a wide range of temperatures and environments, making them suitable for use in a variety of industries.  

How to Calibrate the Flow Rate of a Peristaltic Metering Pump?

How to Calibrate the Flow Rate of a Peristaltic Metering Pump?

For a specific ID  tubing with a certain length, the flow rate of peristaltic pump is proportional to the pump drive speed (RPM) within the linear region of its operation.  The actual flow of a peristaltic pump depends on many factors, such as the fluidics properties (viscosity), the way the tubing installation, system hydraulic resistance (fitting, tubing flow resistance), the tubing stiffness and operation time as well fluid temperature.  These factors cannot be accounted during factory testing and calibration.   The flow rate even changes a little bit after tubing burn-in (first 1-2 hours operation).   One can easily notice that the flow rate of a peristaltic pump gets attenuated.  Calibrating a peristaltic pump becomes necessarily to ensure accurate dispensing of liquids.  The steps can vary based on the specific model and features of your peristaltic pump, but here are general guidelines for calibrating a peristaltic pump with a calibration function.
