+GF+Signet integrated rotary flow meter in large stock
The 2537 rotary flowmeter series features low flow rate, low power, and high resolution, with various output options such as volume pulse
Pulse frequency divider, flow switch, digital (S3L) or 4-20 mA. It can be directly accessed through the built-in user interface
Set up the unit on site.
The 4-20 mA model provides blind current loop output.
The digital (S3L) model provides digital (S3L) output for connecting Signet 8900 multi parameter control
Device or 9900 transmitter.
The composite model uses a single relay (mechanical or solid-state) and has three optional operating modes:
The frequency divider mode can reduce the wheel frequency to adapt to devices with low-frequency inputs.
The accumulation mode can achieve one pulse output for each group of traffic.
The flow switch mode uses a single relay and can perform high or low alarm operations.
A small LCD can be set up on the 2537 without using any external devices. During normal operation period
The display is not visible.
Planting liquids and chemicals.
All plastic materials (including typical pipe types such as PVC, PVDF, PP, etc.)
PE) is more or less permeable to the medium it contains, such as water or volatile compounds
Quality, including some acidity. This effect is not related to porosity, but purely gas permeability
The problem of plastic diffusion.
If the plastic material is compatible with the medium, penetration will not damage the plastic itself. but
Yes, if the plastic contains other sensitive components such as GF Signet plastic wheel conveyors
Sensors may be affected by the diffusion of media into the body and rotor
Or damaged.
There have been reports of PVDF wheel sensors malfunctioning in hot nitric acid applications.
PVDF allows nitric acid components to penetrate without damaging itself. There's no clear here
Accurate guidelines, as the destructive effect on sensors largely depends on
Temperature, pressure, and medium concentration.
It is possible to apply sensors in corrosive media. GF Signet can
Provide sensors with special requirements, whose different internal resin encapsulation can delay acid
The destructive effect on sensors.
Wheel maintenance:
The wheel on the sensor is prone to wear and may require repair and replacement of components (wheel,
Rotating shaft, O-ring, bearing, cage, etc. The maintenance cycle depends on the application environment
It depends on the environment, medium characteristics, and installation. Including but not limited to: process flow rate, water hammer
The appearance of corrosive and abrasive fluids, as well as the surrounding equipment where sensors are installed.
GF Signet provides separate replacement parts and wheel replacement kits, including replacement operations
Provide an instruction manual that allows customers to perform on-site replacement to reduce system downtime.

wiring
Only qualified personnel are allowed to operate the electrical connections of this product.
To use wiring terminals:
1. Rotate the yellow lid counterclockwise by ¼ circle to remove it.
2. Remove the two fixing screws and then remove the black cover plate.
Before connecting the cables to the terminals, please thread all cables through the conduit ports.
The terminal block is suitable for wires with 16-22AWG specifications.
The cable diameter must be 7 mm to 10 mm (0.275 in. to 0.394 in.) to ensure proper sealing in the liquid tight joint.
3. The conduit port has a 1/2-inch NPT thread. After wiring, seal the port with a liquid tight conduit connector (3-9000.392-1) or conduit.
For the installation of conduit:
The threaded conduit has a half inch NPT thread, which can be directly connected to the conduit port.
For conduit with ISO threads, please use the black thread adapter included with the connector kit.
To comply with NEC requirements, do not use any metal conduit during installation.
