Superheated Steam Flow Meter

Superheated Steam Flow Meter

Regarding the customer's requirement for an MO-VFM vortex flow meter (for superheated steam applications), and based on the

 provided parameters (temperature 0-400℃, pressure 40 bar, flow rate 0-35 tons/hour, 24V DC power supply, 4-20mA output, DN150

 diameter), our technicians recommended an isolated replaceable temperature and pressure integrated vortex flow meter. This meter

 is highly compatible in core parameters and optimized for the specific needs of steam measurement. The following is a detailed analysis:

I. Core Parameter Matching Analysis

Customer Required Parameters | Recommended Product Parameters | Matching Conclusion

Medium: Superheated Steam | Recommended product explicitly labeled "Hot Steam," perfect match

Temperature Range: 0-400℃ | Recommended product's upper temperature limit is 400℃, covering the requirements

Pressure Range: 40 bar (approximately 4.0 MPa) | Recommended product's pressure rating is 4.0 MPa, perfect match

Flow Rate Range: 0-35 tons/hour Recommended product nominal capacity: 35 tons/hour (actual value is full scale; vortex flow

 meters typically cannot measure zero flow, but can cover the customer's normal operating range).

Diameter: DN150. Recommended product diameter is DN150, completely identical.

Power Supply and Output: 24V DC power supply, 4-20mA output. Recommended product fully meets these requirements.

Material: Not specified (default requires high temperature resistance). Recommended product uses 304 stainless steel, suitable

 for high-temperature steam environments.

II. Technical Advantages of the Recommended Product

Integrated Temperature and Pressure Design: Integrates temperature and pressure sensors, directly measuring steam density and

 temperature. Built-in algorithms compensate for the influence of temperature and pressure on flow measurement, significantly 

improving measurement accuracy (especially suitable for media with frequently changing operating conditions, such as superheated steam).

Isolated Replaceable Structure: The sensor and measuring tube are designed to be separable, facilitating online maintenance and

 replacement, reducing downtime and maintenance costs.

Vibration Resistance: Employs an anti-vibration probe and noise reduction circuitry to effectively suppress interference from pipeline

 vibration on the measurement signal, ensuring data stability (steam pipelines often generate mechanical noise due to steam flow or

 equipment vibration). LCD Display: Instantaneous flow rate, cumulative flow rate, temperature, pressure, and other parameters can be

 read intuitively on-site, eliminating the need for additional display instruments and simplifying system integration.

III. Details to be Confirmed with the Customer

Flow Rate Limit Requirements: Due to its operating principle, vortex flowmeters cannot truly measure zero flow (no signal output when

 no vortex is generated). It is necessary to confirm with the customer whether their process requires monitoring extremely low flow 

rates (e.g., during start-up and shutdown). If this function is required, consider supplementing with a small flow measurement 

instrument (e.g., orifice plate flowmeter + differential pressure transmitter).

Explosion-proof Rating: If the steam pipeline is located in an explosive environment (e.g., chemical, oil and gas fields), it is necessary

 to confirm whether an explosion-proof type (e.g., ExdIICT6) is required. The recommended product does not specify an explosion-proof 

rating and requires further communication.

Installation Method: The recommended product uses a flange connection. It is necessary to confirm whether the customer's pipeline

 has a flange structure or requires other connection methods (e.g., clamp-on type).

IV. Alternative Solution Recommendations If customers have extremely high accuracy requirements (such as in trade settlement scenarios),

 mass flow meters (such as Coriolis flow meters) can be considered. These can directly measure the mass flow rate of steam without

 temperature and pressure compensation, but the cost is higher. Vortex flow meters still have advantages in terms of cost-effectiveness 

and long-term stability, and are especially suitable for process control scenarios.
