P series quality flow sensor
The P series mass flow meter is composed of the P series mass flow sensor and the DPT type transmitter, achieving an accuracy level of 0.1. Advantages and Features of the P Series Flow Meter: 1. Utilizes a dual-type or dual-C type flow tube design, providing high sensitivity. 2. Fully provides mass flow, volumetric flow, density, temperature measurement, and calculated parameters, allowing for reliable results without complicated conversions, and can directly replace volumetric meters. 3. Easy installation, no need for rectifying or filtering components, and no special installation requirements such as straight pipe sections.

Frequently Asked Questions — P Series Quality Flow Sensor
Q1: What is the operating principle of the P Series Flow Sensor?
A1: The P Series uses high-precision thermal or differential measurement (depending on model) to detect flow rate with quick response times and excellent repeatability.
Q2: Which industries typically use the P Series?
A2: These sensors are popular in pharmaceutical, food & beverage, water treatment, semiconductor, and chemical processing applications requiring accurate and reliable flow monitoring.
Q3: Can the sensor handle aggressive or corrosive media?
A3: Yes, the sensor is constructed with SUS316L stainless steel, offering high resistance to corrosion. Custom configurations may be available for more challenging fluids.
Q4: Are these sensors compatible with digital communication protocols?
A4: Absolutely. Most models support 4–20 mA, pulse output, and RS485 communication, making them easy to integrate into PLC, DCS, or IoT environments.
Q5: Do the sensors require calibration?
A5: The sensors come pre-calibrated from the factory. For critical applications, periodic recalibration is recommended, and field calibration kits may be available.
Q6: What maintenance is required?
A6: Minimal. The modular, compact design ensures easy replacement and cleaning. Regular inspection is advised in harsh operating conditions.
Q7: Are certifications like CE or SIL available?
A7: Yes, select models comply with CE, RoHS, and can be configured to meet SIL requirements for safety-critical systems.
Q8: Can the P Series be installed in vertical pipelines?
A8: Yes, the flow sensors can be installed vertically or horizontally, as long as installation guidelines—especially flow direction—are followed.
