In industrial sites such as chemical, environmental protection, grain & oil, water treatment and metallurgy, accurate monitoring of medium level, flow rate and density is a core link for safe production, stable feeding and energy saving.
From high/low level alarm of storage tanks, continuous liquid level measurement, to pipeline flow metering and real-time medium density detection, working conditions are complex and diverse. Measuring instruments adapted to different mediums, temperatures and pressures are required. Today let’s take a look at a variety of self-developed instruments from Nuoying Jiaye, providing one-stop solutions for industrial measurement challenges.
✅ Tuning Fork Level / Limit Switch (Standard Fork, PTFE Coated Fork, Tuning Fork with Hirschmann Connector)
The tuning fork switch is driven by piezoelectric crystals to generate resonance. When materials touch the fork, the vibration frequency changes. The sensor captures the signal and outputs a switching value to realize high and low liquid/ material level alarm and pump interlock protection.
- Standard fork: Suitable for general liquids such as clean water, oil products and conventional solvents. Easy to install, no on-site calibration required.
- PTFE anti-corrosion coated fork: Probe coated with PTFE, specially used for strong corrosive acid and alkali mediums with excellent corrosion resistance.
- Tuning fork with Hirschmann connector: Simple wiring, compact structure, ideal for limit detection in narrow tanks and pipelines.
Resistant to interference from foam, turbulence and slight scaling. Widely used in chemical storage tanks, sewage pools, silos for overflow and empty bin protection.
✅ Rotary Paddle Level Switch
A classic mechanical level detection product. The motor drives the blade to rotate. When materials block the blade, a switching signal is triggered. Suitable for powder and granular solid materials, such as fly ash, grain, plastic pellets and mineral powder. High temperature resistance and high reliability, a mature option for high/low level alarm of silos.
✅ Radar Level Transmitter
Non-contact continuous liquid level measuring instrument. It emits microwave pulses, which are reflected by the medium surface. The time of flight of signals is calculated to get the level height.
It can measure liquid and solid powder, and is not affected by medium temperature, pressure, steam or dust. Suitable for large storage tanks, reaction kettles, raw coal silos and sewage pools for continuous real-time monitoring. It outputs 4-20mA signals to access DCS system for remote monitoring.
✅ Ultrasonic Flowmeter
Clamp-on / wafer type ultrasonic flowmeter. It measures liquid flow in pipelines by ultrasonic time difference method. No pipe cutting or drilling, installation without production shutdown and no pressure loss. It is used to measure the flow of clean water, sewage, oil and other mediums, widely applied in water supply & drainage, circulating water and chemical pipeline flow metering projects. Complete certificates are provided with simple on-site commissioning.
✅ Tank Side Indicator
On-site local display instrument for storage tanks. It can directly read the liquid level value inside the tank without power supply. Even if the central control system loses power, field personnel can check the tank liquid level directly, serving as redundant backup for remote transmitters to ensure storage tank safety, essential for petroleum and chemical storage tanks.
✅ Tuning Fork Density Meter
Online liquid density & concentration measuring instrument based on tuning fork vibration principle. Changes in medium density alter the resonant frequency of the tuning fork, which is converted into density signals. It can monitor acid & alkali solutions, slurry, brine and other mediums in real time, used for concentration proportioning and process purification. Supports in-line and insertion installation for continuous online monitoring without sampling test.
