Product Overview
The ZZYS30 vortex flowmeter is a highly versatile velocity flow instrument designed for a broad spectrum of applications.
Ideal for measuring, monitoring, and controlling the flow of liquids, steam, and a wide array of gases.
Boasting an innovative structure, it resists mechanical vibrations, impacts, and contamination, ensuring longevity and reliability.
With no moving parts, wear and tear, or need for mechanical maintenance, it guarantees low pressure loss, stable performance, and exceptional accuracy.
Simple to install, the sensor and signal converter can be easily matched to meet specific needs.
Product features:
Extensively applicable, perfect for measuring flow in steam, gas, and liquid industries.
Superior vibration resistance, zero drift at zero point, effectively neutralizing the impact of external vibrations.
The ZZY30 model offers integrated temperature and pressure options, reducing installation costs for users.
Provides (0-5) kHz frequency output, (4-20) mA output, or HART/Modbus communication protocols.
Supports parameter settings via Bluetooth communication. Wear and dirt resistant, it requires no mechanical maintenance, offers an extended service life, and is explosion-proof for utmost safety.

Installation Requirements
Piping Condition
The installation of the vortex flowmeter necessitates a specific length of straight pipe both before and after the device. The common scenarios are as follows (D represents the diameter of the pipe):
1.
Ensure the sensor is installed on a pipe—whether horizontal, vertical, or inclined (with liquid flowing from bottom to top)—with a diameter identical to the sensor. The straight pipe length upstream should adhere to 15-20D, and downstream should maintain 5-10D.
2.
The pipeline near the liquid sensor must be fully filled with the liquid to be measured.
3.
Avoid installing the sensor on pipes experiencing significant mechanical vibrations.
4.
The inner diameter of the straight pipe section should ideally match the sensor diameter. If they vary, choose a slightly larger pipe, ensuring an error margin of ≤3% and not exceeding 5mm. Sensors should not be installed in areas with strong electromagnetic interference, confined spaces, or where maintenance is challenging..
5.
Horizontal pipeline installation is most prevalent for flow sensors. For gas flow containing minor liquid amounts, position the sensor at a higher pipeline point. Conversely, for liquid flow with minor gas inclusions, place the sensor at a lower point in the pipeline.
6.
Vertical pipeline sensor installation: For gas flow, install on a vertical pipeline with no flow direction restrictions. If the gas includes minor liquid, ensure the flow is from bottom to top. For liquid flow, ensure the flow is from bottom to top to prevent additional weight on the probe.
7.
Side-mounting sensors on horizontal pipelines is suitable for any fluid, especially superheated steam, saturated steam, and low-temperature liquids. Side mounting is preferred when possible to reduce temperature impact on the amplifier.
8.
Inverted sensor installation on horizontal pipelines is generally discouraged. It is unsuitable for general gas or superheated steam measurement but can be used for saturated steam and high-temperature liquids, or when pipelines need frequent cleaning.
9.
For pipelines with insulation layers, particularly when measuring high-temperature steam, the insulation should not exceed one-third of the bracket height.
10.
Choosing pressure and temperature measurement points: Depending on requirements, place the pressure measurement point 3-5D downstream of the sensor, and the temperature measurement point 6-8D downstream.
