Product Overview
The ZZYS30 Vortex Flowmeter is an advanced velocity flow instrument designed for a diverse array of applications.
Perfect for measuring, monitoring, and controlling the flow of liquids, steam, and a wide variety of gases.
Boasting a revolutionary design, it is highly resistant to mechanical vibrations, impacts, and contamination.
With a construction that includes no moving parts, the flowmeter offers zero wear and tear, requires no mechanical maintenance, ensures low pressure loss, maintains stable performance, and delivers exceptional accuracy.
Installation is a breeze, with the sensor and signal converter being compatible and adaptable to your specific needs.
Product Features:
Extensive application range, ideal for measuring the flow of steam, gas, and liquids.
Superior vibration resistance, zero drift at the zero point, effectively neutralizing the impact of external vibrations.
The ZZY30 provides integrated temperature and pressure options, offering significant installation cost savings for users.
Multiple output options including (0-5) kHz frequency output, (4-20) mA output, or HART communication/Modbus protocol communication.
Supports parameter configuration via Bluetooth communication. Designed to be wear-resistant, dirt-resistant, maintenance-free, with a long service life and explosion-proof for enhanced safety.

Installation Requirements
Piping Condition
For optimal performance, the installation of the vortex flowmeter requires a specific length of straight pipe section both upstream and downstream. These requirements are as follows (D represents the pipe diameter):
1.
The sensor should be mounted on a pipe that is either horizontal, vertical, or inclined (with liquid flowing upwards). The pipe must have the same diameter as the sensor. Ensure a straight pipe section of 15-20D upstream and 5-10D downstream of the sensor for accurate readings.
2.
The pipe near the liquid sensor must be fully filled with the liquid being measured.
3.
Avoid installing the sensor on pipes subject to strong mechanical vibrations.
4.
Maintain consistent inner diameters for the straight pipe sections and the sensor. If an exact match is not possible, use a slightly larger pipe with an error margin of ≤3%, not exceeding 5mm. Do not install the sensor where there is strong electromagnetic interference, space constraints, or inconvenient maintenance conditions..
5.
Horizontal pipeline installation is most common. When measuring gas flow containing a small amount of liquid, place the sensor at a higher point in the pipeline. When measuring liquid flow containing a small amount of gas, install the sensor at a lower point in the pipeline.
6.
For vertical pipeline installation, the sensor can measure gas flow with no flow direction restrictions. If the gas contains a small amount of liquid, ensure the flow is from bottom to top. For liquid flow, the sensor should be installed with flow from bottom to top to prevent added weight on the probe.
7.
Side-mounted sensors on horizontal pipelines are versatile, suitable for superheated steam, saturated steam, and low-temperature liquids. This method is preferred where possible, as it reduces temperature impact on the amplifier.
8.
Inverted sensor installation on horizontal pipelines is generally not recommended for measuring general gases or superheated steam but can be used for saturated steam and high-temperature liquids especially where frequent cleaning is required.
9.
When installing sensors on pipelines with insulation layers, ensure the insulation does not exceed one-third of the bracket height when measuring high-temperature steam.
10.
Selecting pressure and temperature measurement points is crucial. Position the pressure measurement point 3-5D downstream and the temperature measurement point 6-8D downstream of the sensor.
